2007-07-17mm: clean up and kernelify shrinker registrationRusty Russell
I can never remember what the function to register to receive VM pressure is called. I have to trace down from __alloc_pages() to find it. It's called "set_shrinker()", and it needs Your Help. 1) Don't hide struct shrinker. It contains no magic. 2) Don't allocate "struct shrinker". It's not helpful. 3) Call them "register_shrinker" and "unregister_shrinker". 4) Call the function "shrink" not "shrinker". 5) Reduce the 17 lines of waffly comments to 13, but document it properly.

2007-07-14[XFS] Quota inode has no parent.David Chinner
Avoid using a special "zero inode" as the parent of the quota inode as this can confuse the filestreams code into thinking the quota inode has a parent. We do not want the quota inode to follow filestreams allocation rules, so pass a NULL as the parent inode and detect this condition when doing stream associations.

2007-05-08[XFS] Fix uquota and oquota enforcement problems.Kouta Ooizumi
When uquota and oquota (gquota/pquota) are enabled for accounting both are enforced if ether has enforcement active. Conditions: - Both XFS_UQUOTA_ACCT and XFS_GQUOTA_ACCT are enabled. - Either XFS_UQUOTA_ENFD or XFS_OQUOTA_ENFD is enabled. - The usage without enforce is reached at the soft limit. Problems: 1. "repquota" shows all grace time even if no enforcement. 2. we cannot make a file over a hard limits even if no enforcement.

2007-05-08[XFS] Invalidate quotacheck when mounting without a quota type.Donald Douwsma
When quotas are mounted or remounted without a particular quota type the quota accounting for that type becomes invalid. Previously we were ignoring this leading to accounting errors.

2007-02-10[XFS] Remove unused header files for MAC and CAP checking functionality.Eric Sandeen
xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has. If this functionality ever goes into Linux, it will be provided at a different layer, most likely through the security hooks in the kernel so we will never need this functionality in XFS.

2007-02-10[XFS] Keep stack usage down for 4k stacks by using noinline.David Chinner
gcc-4.1 and more recent aggressively inline static functions which increases XFS stack usage by ~15% in critical paths. Prevent this from occurring by adding noinline to the STATIC definition. Also uninline some functions that are too large to be inlined and were causing problems with CONFIG_FORCED_INLINING=y. Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.
