  • 8e1f936b7   mm: clean up and kernelify shrinker registration ... Browse Code »

    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.

  • b11f94d53   [XFS] Quota inode has no parent. ... Browse Code »

    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.

  • 7bc5306d7   [XFS] Remove unused header files for MAC and CAP checking functionality. ... Browse Code »

    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.

    Patch provided by Eric Sandeen (sandeen@sandeen.net).

  • 7989cb8ef   [XFS] Keep stack usage down for 4k stacks by using noinline. ... Browse Code »

    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.

  • 4eea22f01   [XFS] 929045 567344 This mod re-organizes some of the in-core file extent ... Browse Code »

    code to prepare for an upcoming mod which will introduce multi-level
    in-core extent allocations. Although the in-core extent management is
    using a new code path in this mod, the functionality remains the same.
    Major changes include: - Introduce 10 new subroutines which re-orgainze
    the existing code but do NOT change functionality:
    xfs_iext_get_ext() xfs_iext_insert() xfs_iext_add()
    xfs_iext_remove() xfs_iext_remove_inline()
    xfs_iext_remove_direct() xfs_iext_realloc_direct()
    xfs_iext_direct_to_inline() xfs_iext_inline_to_direct()
    xfs_iext_destroy() - Remove 2 subroutines (functionality moved to new
    subroutines above): xfs_iext_realloc() -replaced by xfs_iext_add()
    and xfs_iext_remove() xfs_bmap_insert_exlist() - replaced by
    xfs_iext_insert() xfs_bmap_delete_exlist() - replaced by
    xfs_iext_remove() - Replace all hard-coded (indexed) extent assignments
    with a call to xfs_iext_get_ext() - Replace all extent record pointer
    arithmetic (ep++, ep--, base + lastx,..) with calls to
    xfs_iext_get_ext() - Update comments to remove the idea of a single
    "extent list" and introduce "extent record" terminology instead
