Before this patch, multi-block reservation structures were allocated from a special slab. This patch folds the structure into the gfs2_inode structure. The disadvantage is that the gfs2_inode needs more memory, even when a file is opened read-only. The advantages are: (a) we don't need the special slab and the extra time it takes to allocate and deallocate from it. (b) we no longer need to worry that the structure exists for things like quota management. (c) This also allows us to remove the calls to get_write_access and put_write_access since we know the structure will exist. Signed-off-by:

This patch basically reverts the majority of patch 5407e242 . That patch eliminated the gfs2_qadata structure in favor of just using the reservations structure. The problem with doing that is that it increases the size of the reservations structure. That is not an issue until it comes time to fold the reservations structure into the inode in memory so we know it's always there. By separating out the quota structure again, we aren't punishing the non-quota users by making all the inodes bigger, requiring more slab space. This patch creates a new slab area to allocate the quota stuff so it's managed a little more sanely. Signed-off-by:

Instead of submitting a READ_SYNC bio for the inode and a READA bio for the inode's extended attributes through submit_bh, submit a single READ_SYNC bio for both through submit_bio when possible. This can be more efficient on some kinds of block devices. Signed-off-by:

When gfs2 allocates an inode and its extended attribute block next to each other at inode create time, the inode's directory entry indicates that in de_rahead. In that case, we can readahead the extended attribute block when we read in the inode. Signed-off-by:

The code it refers to is the rht_for_each_entry_safe usage in glock_hash_walk. The condition that triggers the warning is lockdep_rht_bucket_is_held(tbl, hash) which is checked in the __rcu_dereference_protected macro. The rhashtable buckets are not changed in glock_hash_walk so it's safe to rely on the rcu protection. Replace the rht_for_each_entry_safe() usage with rht_for_each_entry_rcu(), which doesn't care whether the bucket lock is held if the rcu read lock is held. Signed-off-by:

When new files and directories are created inside a parent directory we automatically inherit the GFS2_DIF_SYSTEM flag (if set) and assign it to the new file/dirs. All new system files/dirs created in the metafs by, say gfs2_jadd, will have this flag set because they will have parent directories in the metafs whose GFS2_DIF_SYSTEM flag has already been set (most likely by a previous mkfs.gfs2) Signed-off-by:

The ELF binary loader in binfmt_elf.c requires an MMU, making it impossible to use regular ELF binaries on NOMMU archs. However, the FDPIC ELF loader in binfmt_elf_fdpic.c is fully capable as a loader for plain ELF, which requires constant displacements between LOAD segments, since it already supports FDPIC ELF files flagged as needing constant displacement. This patch adjusts the FDPIC ELF loader to accept non-FDPIC ELF files on NOMMU archs. They are treated identically to FDPIC ELF files with the constant-displacement flag bit set, except for personality, which must match the ABI of the program being loaded; the PER_LINUX_FDPIC personality controls how the kernel interprets function pointers passed to sigaction. Files that do not set a stack size requirement explicitly are given a default stack size (matching the amount of committed stack the normal ELF loader for MMU archs would give them) rather than being rejected; this is necessary because plain ELF files generally do not declare stack requirements in theit program headers. Only ET_DYN (PIE) format ELF files are supported, since loading at a fixed virtual address is not possible on NOMMU. This patch was developed and tested on J2 (SH2-compatible) but should be usable immediately on all archs where binfmt_elf_fdpic is available. Moreover, by providing dummy definitions of the elf_check_fdpic() and elf_check_const_displacement() macros for archs which lack an FDPIC ABI, it should be possible to enable building of binfmt_elf_fdpic on all other NOMMU archs and thereby give them ELF binary support, but I have not yet tested this. The motivation for using binfmt_elf_fdpic.c rather than adapting binfmt_elf.c to NOMMU is that the former already has all the necessary code to work properly on NOMMU and has already received widespread real-world use and testing. I hope this is not controversial. I'm not really happy with having to unset the FDPIC_FUNCPTRS personality bit when loading non-FDPIC ELF. This bit should really reset automatically on execve, since otherwise, executing non-ELF binaries (e.g. bFLT) from an FDPIC process will leave the personality in the wrong state and severely break signal handling. But that's a separate, existing bug and I don't know the right place to fix it. Signed-off-by:

EXTRA_CFLAGS are intended to be used on the command line, not by Kbuild. In case of cxgbi drivers, use of EXTRA_CFLAGS results in a compilation failure: drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:24:21: fatal error: t4_regs.h: No such file or directory when building like: $ make drivers/scsi/cxgbi/ EXTRA_CFLAGS=-Wwhatever Use ccflags-y instead of EXTRA_CFLAGS.
