  • 579aa9caf   [XFS] shrink mrlock_t ... Browse Code »

    The writer field is not needed for non_DEBU builds so remove it. While
    we're at i also clean up the interface for is locked asserts to go through
    and xfs_iget.c helper with an interface like the xfs_ilock routines to
    isolated the XFS codebase from mrlock internals. That way we can kill
    mrlock_t entirely once rw_semaphores grow an islocked facility. Also
    remove unused flags to the ilock family of functions.

  • db7a19f2c   [XFS] Ensure xfs_bawrite() errors are checked. ... Browse Code »

    xfs_bawrite() can return immediate error status on async writes. Unlike
    xfsbdstrat() we don't ever check the error on the buffer after the call,
    so we currently do not catch errors at all here. Ensure we catch and
    propagate or warn to the syslog about up-front async write errors.

  • 5d51eff45   [XFS] Fix inode allocation latency ... Browse Code »

    The log force added in xfs_iget_core() has been a performance issue since
    it was introduced for tight loops that allocate then unlink a single file.
    under heavy writeback, this can introduce unnecessary latency due tothe
    log I/o getting stuck behind bulk data writes.

    Fix this latency problem by avoinding the need for the log force by moving
    the place we mark linux inode dirty to the transaction commit rather than
    on transaction completion.

    This also closes a potential hole in the sync code where a linux inode is
    not dirty between the time it is modified and the time the log buffer has
    been written to disk.

  • 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.
