On a box with a lot of ram (148gb) I can make the box softlockup after running an fs_mark job that creates hundreds of millions of empty files. This is because we never generate enough memory pressure to keep the number of inodes on our unused list low, so when we go to unmount we have to evict ~100 million inodes. This makes one processor a very unhappy person, so add a cond_resched() in dispose_list() and if we need a resched when processing the s_inodes list do that and run dispose_list() on what we've currently culled.

There's a small consistency problem between the inode and writeback naming. Writeback calls the "for IO" inode queues b_io and b_more_io, but the inode calls these the "writeback list" or i_wb_list. This makes it hard to an new "under writeback" list to the inode, or call it an "under IO" list on the bdi because either way we'll have writeback on IO and IO on writeback and it'll just be confusing. I'm getting confused just writing this! So, rename the inode "for IO" list variable to i_io_list so we can add a new "writeback list" in a subsequent patch. Signed-off-by:

When competing sync(2) calls walk the same filesystem, they need to walk the list of inodes on the superblock to find all the inodes that we need to wait for IO completion on. However, when multiple wait_sb_inodes() calls do this at the same time, they contend on the the inode_sb_list_lock and the contention causes system wide slowdowns. In effect, concurrent sync(2) calls can take longer and burn more CPU than if they were serialised. Stop the worst of the contention by adding a per-sb mutex to wrap around wait_sb_inodes() so that we only execute one sync(2) IO completion walk per superblock superblock at a time and hence avoid contention being triggered by concurrent sync(2) calls.

The process of reducing contention on per-superblock inode lists starts with moving the locking to match the per-superblock inode list. This takes the global lock out of the picture and reduces the contention problems to within a single filesystem. This doesn't get rid of contention as the locks still have global CPU scope, but it does isolate operations on different superblocks form each other. Signed-off-by:

Some filesystems don't use the VFS inode hash and fake the fact they are hashed so that all the writeback code works correctly. However, this means the evict() path still tries to remove the inode from the hash, meaning that the inode_hash_lock() needs to be taken unnecessarily. Hence under certain workloads the inode_hash_lock can be contended even if the inode is never actually hashed. To avoid this add hlist_fake to test if the inode isn't actually hashed to avoid taking the hash lock on inodes that have never been hashed. Based on Dave Chinner's inode: add IOP_NOTHASHED to avoid inode hash lock in evict basd on Al's suggestions. Thanks, Signed-off-by:

Doing writeback on lots of little files causes terrible IOPS storms because of the per-mapping writeback plugging we do. This essentially causes imeediate dispatch of IO for each mapping, regardless of the context in which writeback is occurring. IOWs, running a concurrent write-lots-of-small 4k files using fsmark on XFS results in a huge number of IOPS being issued for data writes. Metadata writes are sorted and plugged at a high level by XFS, so aggregate nicely into large IOs. However, data writeback IOs are dispatched in individual 4k IOs, even when the blocks of two consecutively written files are adjacent. Test VM: 8p, 8GB RAM, 4xSSD in RAID0, 100TB sparse XFS filesystem, metadata CRCs enabled. Kernel: 3.10-rc5 + xfsdev + my 3.11 xfs queue (~70 patches) Test: $ ./fs_mark -D 10000 -S0 -n 10000 -s 4096 -L 120 -d /mnt/scratch/0 -d /mnt/scratch/1 -d /mnt/scratch/2 -d /mnt/scratch/3 -d /mnt/scratch/4 -d /mnt/scratch/5 -d /mnt/scratch/6 -d /mnt/scratch/7 Result: wall sys create rate Physical write IO time CPU (avg files/s) IOPS Bandwidth ----- ----- ------------ ------ --------- unpatched 6m56s 15m47s 24,000+/-500 26,000 130MB/s patched 5m06s 13m28s 32,800+/-600 1,500 180MB/s improvement -26.44% -14.68% +36.67% -94.23% +38.46% If I use zero length files, this workload at about 500 IOPS, so plugging drops the data IOs from roughly 25,500/s to 1000/s. 3 lines of code, 35% better throughput for 15% less CPU. The benefits of plugging at this layer are likely to be higher for spinning media as the IO patterns for this workload are going make a much bigger difference on high IO latency devices.....

The 'wacom_wireless_work' function does not recalculate the tablet's resolution, causing the value contained in the 'features' struct to always be reported to userspace. This value is valid only for the pen interface, meaning that the value will be incorrect for the touchpad (if present). This in particular causes problems for libinput which relies on the reported resolution being correct. This patch adds the necessary calls to recalculate the resolution for each interface. This requires a little bit of code shuffling since both the 'wacom_set_default_phy' and 'wacom_calculate_res' are declared below their new first point of use in 'wacom_wireless_work'. Signed-off-by:

It was possible for a synchronous update of the RX index in the error case to get ahead of the asynchronous RX index update in the normal case. Change the RX processing to preserve an RX completion order. There were two error cases. First, if a buffer is not present to receive data, there would be no queue entry to preserve the RX completion order. Instead of dropping the RX frame, leave the RX frame in the ring. Schedule RX processing when RX entries are enqueued, in case there are RX frames waiting in the ring to be received. Second, if a buffer is too small to receive data, drop the frame in the ring, mark the RX entry as done, and indicate the error in the RX entry length. Check for a negative length in the receive callback in ntb_netdev, and count occurrences as rx_length_errors. Signed-off-by:

There has been a subtle race in setting the other entry's global bit since ~ 2000 but it take particularly pathological workloads that essentially do mostly vmalloc/vfree to trigger this. This pull request fixes the 64-bit case but leaves the case of 32 bit CPUs with 64 bit ptes unsolved for now. The unfixed cases affect hardware that is not available in the field yet. - Instruction emulation requires loading instructions from user space but the current fast but simplistic approach will fail on pages that are PROT_EXEC but !PROT_READ.

Pull drm fixes from Daniel Vetter: "One i915 regression fix and a drm core one since Dave's not around, both introduced in 4.2 so not cc: stable. The fix for the warning Ted reported isn't in here yet since he didn't yet supply a tested-by and I can't repro this one myself (it's in fixup code that needs firmware doing something i915 wouldn't do)" * tag 'drm-intel-fixes-2015-08-07' of git://anongit.freedesktop.org/drm-intel: drm/vblank: Use u32 consistently for vblank counters drm/i915: Allow parsing of variable size child device entries from VBT
