    It does, thanks :)

    Does this problem exist in 2.16.6.x??

    From various comments like:
    Unless 2.6.16.x is a dead-end could we please also have this patch put
    into there?
    a result (I believe) of the corruption bug that was in 2.6.16/17.
    I just want to confirm this bug as well and unfortunately it was my
    system disk too who had to take the hit. Im running 2.6.16
    I assume it does.

    But the FAQ says:
    Q: What is the issue with directory corruption in Linux 2.6.17?
    In the Linux kernel 2.6.17 release a subtle bug...

    which implies it's not...


    So given this is from
    * One less used entry in the free table.
    INT_MOD(free->hdr.nused, ARCH_CONVERT, -1);
    xfs_dir2_free_log_header(tp, fbp);

    and it looks awfully similar to the patch which says:

    --- linux-
    +++ linux-
    @@ -970,7 +970,7 @@ xfs_dir2_leafn_remove(
    * One less used entry in the free table.
    - free->hdr.nused = cpu_to_be32(-1);
    + be32_add(&free->hdr.nused, -1);
    xfs_dir2_free_log_header(tp, fbp);

    Should 2.6.16.x replace
    INT_MOD(free->hdr.nused, ARCH_CONVERT, -1);
    be32_add(&free->hdr.nused, -1);
    I hope so because I assumed there simply wasn't a patch for 2.6.16 and
    applied this 'best guess' to my servers and rebooted/remounted successfully.
