Pull xfs update from Ben Myers: "This is primarily bug fixes, many of which you already have. New stuff includes a series to decouple the in-memory and on-disk log format, helpers in the area of inode clusters, and i_version handling. We decided to try to use more topic branches this release, so there are some merge commits in there on account of that. I'm afraid I didn't do a good job of putting meaningful comments in the first couple of merges. Sorry about that. I think I have the hang of it now. For 3.14-rc1 there are fixes in the areas of remote attributes, discard, growfs, memory leaks in recovery, directory v2, quotas, the MAINTAINERS file, allocation alignment, extent list locking, and in xfs_bmapi_allocate. There are cleanups in xfs_setsize_buftarg, removing unused macros, quotas, setattr, and freeing of inode clusters. The in-memory and on-disk log format have been decoupled, a common helper to calculate the number of blocks in an inode cluster has been added, and handling of i_version has been pulled into the filesystems that use it. - cleanup in xfs_setsize_buftarg - removal of remaining unused flags for vop toss/flush/flushinval - fix for memory corruption in xfs_attrlist_by_handle - fix for out-of-date comment in xfs_trans_dqlockedjoin - fix for discard if range length is less than one block - fix for overrun of agfl buffer using growfs on v4 superblock filesystems - pull i_version handling out into the filesystems that use it - don't leak recovery items on error - fix for memory leak in xfs_dir2_node_removename - several cleanups for quotas - fix bad assertion in xfs_qm_vop_create_dqattach - cleanup for xfs_setattr_mode, and add xfs_setattr_time - fix quota assert in xfs_setattr_nonsize - fix an infinite loop when turning off group/project quota before user quota - fix for temporary buffer allocation failure in xfs_dir2_block_to_sf with large directory block sizes - fix Dave's email address in MAINTAINERS - cleanup calculation of freed inode cluster blocks - fix alignment of initial file allocations to match filesystem geometry - decouple in-memory and on-disk log format - introduce a common helper to calculate the number of filesystem blocks in an inode cluster - fixes for extent list locking - fix for off-by-one in xfs_attr3_rmt_verify - fix for missing destroy_work_on_stack in xfs_bmapi_allocate" * tag 'xfs-for-linus-v3.14-rc1' of git://oss.sgi.com/xfs/xfs: (51 commits) xfs: Calling destroy_work_on_stack() to pair with INIT_WORK_ONSTACK() xfs: fix off-by-one error in xfs_attr3_rmt_verify xfs: assert that we hold the ilock for extent map access xfs: use xfs_ilock_attr_map_shared in xfs_attr_list_int xfs: use xfs_ilock_attr_map_shared in xfs_attr_get xfs: use xfs_ilock_data_map_shared in xfs_qm_dqiterate xfs: use xfs_ilock_data_map_shared in xfs_qm_dqtobp xfs: take the ilock around xfs_bmapi_read in xfs_zero_remaining_bytes xfs: reinstate the ilock in xfs_readdir xfs: add xfs_ilock_attr_map_shared xfs: rename xfs_ilock_map_shared xfs: remove xfs_iunlock_map_shared xfs: no need to lock the inode in xfs_find_handle xfs: use xfs_icluster_size_fsb in xfs_imap xfs: use xfs_icluster_size_fsb in xfs_ifree_cluster xfs: use xfs_icluster_size_fsb in xfs_ialloc_inode_init xfs: use xfs_icluster_size_fsb in xfs_bulkstat xfs: introduce a common helper xfs_icluster_size_fsb xfs: get rid of XFS_IALLOC_BLOCKS macros xfs: get rid of XFS_INODE_CLUSTER_SIZE macros ...

Pull Xen updates from Konrad Rzeszutek Wilk: "Two major features that Xen community is excited about: The first is event channel scalability by David Vrabel - we switch over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO queue with priorities. This lets us be able to handle more events, have lower latency, and better scalability. Good stuff. The other is PVH by Mukesh Rathor. In short, PV is a mode where the kernel lets the hypervisor program page-tables, segments, etc. With EPT/NPT capabilities in current processors, the overhead of doing this in an HVM (Hardware Virtual Machine) container is much lower than the hypervisor doing it for us. In short we let a PV guest run without doing page-table, segment, syscall, etc updates through the hypervisor - instead it is all done within the guest container. It is a "hybrid" PV - hence the 'PVH' name - a PV guest within an HVM container. The major benefits are less code to deal with - for example we only use one function from the the pv_mmu_ops (which has 39 function calls); faster performance for syscall (no context switches into the hypervisor); less traps on various operations; etc. It is still being baked - the ABI is not yet set in stone. But it is pretty awesome and we are excited about it. Lastly, there are some changes to ARM code - you should get a simple conflict which has been resolved in #linux-next. In short, this pull has awesome features. Features: - FIFO event channels. Key advantages: support for over 100,000 events (2^17), 16 different event priorities, improved fairness in event latency through the use of FIFOs. - Xen PVH support. "It’s a fully PV kernel mode, running with paravirtualized disk and network, paravirtualized interrupts and timers, no emulated devices of any kind (and thus no qemu), no BIOS or legacy boot — but instead of requiring PV MMU, it uses the HVM hardware extensions to virtualize the pagetables, as well as system calls and other privileged operations." (from "The Paravirtualization Spectrum, Part 2: From poles to a spectrum") Bug-fixes: - Fixes in balloon driver (refactor and make it work under ARM) - Allow xenfb to be used in HVM guests. - Allow xen_platform_pci=0 to work properly. - Refactors in event channels" * tag 'stable/for-linus-3.14-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: (52 commits) xen/pvh: Set X86_CR0_WP and others in CR0 (v2) MAINTAINERS: add git repository for Xen xen/pvh: Use 'depend' instead of 'select'. xen: delete new instances of __cpuinit usage xen/fb: allow xenfb initialization for hvm guests xen/evtchn_fifo: fix error return code in evtchn_fifo_setup() xen-platform: fix error return code in platform_pci_init() xen/pvh: remove duplicated include from enlighten.c xen/pvh: Fix compile issues with xen_pvh_domain() xen: Use dev_is_pci() to check whether it is pci device xen/grant-table: Force to use v1 of grants. xen/pvh: Support ParaVirtualized Hardware extensions (v3). xen/pvh: Piggyback on PVHVM XenBus. xen/pvh: Piggyback on PVHVM for grant driver (v4) xen/grant: Implement an grant frame array struct (v3). xen/grant-table: Refactor gnttab_init xen/grants: Remove gnttab_max_grant_frames dependency on gnttab_init. xen/pvh: Piggyback on PVHVM for event channels (v2) xen/pvh: Update E820 to work with PVH (v2) xen/pvh: Secondary VCPU bringup (non-bootup CPUs) ...

The actions are: o trace on/off - enable or disable tracing o snapshot - save the current trace buffer in the snapshot o stacktrace - dump the current stack trace to the ringbuffer o enable/disable events - enable or disable another event Namhyung Kim added updates to the tracing uprobes code. Having the uprobes add support for fetch methods. The rest are various bug fixes with the new code, and minor ones for the old code" * tag 'trace-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (38 commits) tracing: Fix buggered tee(2) on tracing_pipe tracing: Have trace buffer point back to trace_array ftrace: Fix synchronization location disabling and freeing ftrace_ops ftrace: Have function graph only trace based on global_ops filters ftrace: Synchronize setting function_trace_op with ftrace_trace_function tracing: Show available event triggers when no trigger is set tracing: Consolidate event trigger code tracing: Fix counter for traceon/off event triggers tracing: Remove double-underscore naming in syscall trigger invocations tracing/kprobes: Add trace event trigger invocations tracing/probes: Fix build break on !CONFIG_KPROBE_EVENT tracing/uprobes: Add @+file_offset fetch method uprobes: Allocate ->utask before handler_chain() for tracing handlers tracing/uprobes: Add support for full argument access methods tracing/uprobes: Fetch args before reserving a ring buffer tracing/uprobes: Pass 'is_return' to traceprobe_parse_probe_arg() tracing/probes: Implement 'memory' fetch method for uprobes tracing/probes: Add fetch{,_size} member into deref fetch method tracing/probes: Move 'symbol' fetch method to kprobes tracing/probes: Implement 'stack' fetch method for uprobes ...

If a node page is trucated, we'd better drop the page in the node_inode's page cache for better memory footprint. Signed-off-by:

open/release operations require userspace transitions to keep track of the open count and to perform any FS-specific setup. However, for some purely read-only FSs which don't need to perform any setup at open/release time, we can avoid the performance overhead of calling into userspace for open/release calls. This patch adds the necessary support to the fuse kernel modules to prevent open/release operations from hitting in userspace. When the client returns ENOSYS, we avoid sending the subsequent release to userspace, and also remember this so that future opens also don't trigger a userspace operation. Signed-off-by:

Various read operations (e.g. readlink, readdir) invalidate the cached attrs for atime changes. This patch adds a new function 'fuse_invalidate_atime', which checks for a read-only super block and avoids the attr invalidation in that case. Signed-off-by:

Having this struct in module memory could Oops when if the module is unloaded while the buffer still persists in a pipe. Since sock_pipe_buf_ops is essentially the same as fuse_dev_pipe_buf_steal merge them into nosteal_pipe_buf_ops (this is the same as default_pipe_buf_ops except stealing the page from the buffer is not allowed).

As the orphan_blocks may be max to 504, so it is not security and rigorous to store such a large array in the kernel stack as Dan Carpenter said. In fact, grab_meta_page has locked the page in the page cache, and we can use find_get_page() to fetch the page safely in the downstream, so we can remove the page array directly. Reported-by:

In the cluster evironment, cluster write has poor performance because userspace_flush() has to contact a userspace program (cmirrord) for clear/mark/flush requests. But both mark and flush requests require cmirrord to communicate the message to all the cluster nodes for each flush call. This behaviour is really slow. To address this we now merge mark and flush requests together to reduce the kernel-userspace-kernel time. We allow a new directive, "integrated_flush" that can be used to instruct the kernel log code to combine flush and mark requests when directed by userspace. If not directed by userspace (due to an older version of the userspace code perhaps), the kernel will function as it did previously - preserving backwards compatibility. Additionally, flush requests are performed lazily when only clear requests exist. Signed-off-by:
