  • 7ae444072   xfs: remove XFS_QMOPT_DQSUSER ... Browse Code »

    Just read the id 0 dquot from disk directly in xfs_qm_init_quotainfo instead
    of going through dqget and requiring a special flag to not add the dquot to
    any lists.

  • 92678554a   xfs: flatten the dquot lock ordering ... Browse Code »

    Introduce a new XFS_DQ_FREEING flag that tells lookup and mplist walks
    to skip a dquot that is beeing freed, and use this avoid the trylock
    on the hash and mplist locks in xfs_qm_dqreclaim_one. Also simplify
    xfs_dqpurge by moving the inodes to a dispose list after marking them
    XFS_DQ_FREEING and avoid the locker ordering constraints.

  • be7ffc38a   xfs: implement lazy removal for the dquot freelist ... Browse Code »

    Do not remove dquots from the freelist when we grab a reference to them in
    xfs_qm_dqlookup, but leave them on the freelist util scanning notices that
    they have a reference. This speeds up the lookup fastpath, and greatly
    simplifies the lock ordering constraints. Note that the same scheme is
    used by the VFS inode and dentry caches.

    Free dquots when purging them during umount instead of keeping them around
    on the freelist in a degraded state. The out of order locking in
    xfs_qm_dqpurge will be removed again later in this series.

    Now that we can't have any dirty dquots around that aren't in the AIL we
    can get rid of the explicit dquot syncing from xfssyncd and xfs_fs_sync_fs
    and instead rely on AIL pushing to write out any quota updates.

  • a0fa2b679   xfs: Convert xlog_warn to new logging interface ... Browse Code »

    Convert the xfs log operations to use the new error logging
    interfaces. This removes the xlog_{warn,panic} wrappers and makes
    almost all errors emit the device they belong to instead of just
    refering to "XFS".

  • 20026d920   xfs: kill the unused XFS_QMOPT_* flush flags V2 ... Browse Code »

    dquots are never flushed asynchronously. Remove the flag and the
    async write support from the flush function. Make the default flush
    a delwri flush to make the inode flush code, which leaves the
    XFS_QMOPT_SYNC the only flag remaining. Convert that to use
    SYNC_WAIT instead, just like the inode flush code.

    V2:
    - just pass flush flags straight through

  • 0b1b213fc   xfs: event tracing support ... Browse Code »

    Convert the old xfs tracing support that could only be used with the
    out of tree kdb and xfsidbg patches to use the generic event tracer.

    To use it make sure CONFIG_EVENT_TRACING is enabled and then enable
    all xfs trace channels by:

    echo 1 > /sys/kernel/debug/tracing/events/xfs/enable

    or alternatively enable single events by just doing the same in one
    event subdirectory, e.g.

    echo 1 > /sys/kernel/debug/tracing/events/xfs/xfs_ihold/enable

    or set more complex filters, etc. In Documentation/trace/events.txt
    all this is desctribed in more detail. To reads the events do a

    cat /sys/kernel/debug/tracing/trace

    Compared to the last posting this patch converts the tracing mostly to
    the one tracepoint per callsite model that other users of the new
    tracing facility also employ. This allows a very fine-grained control
    of the tracing, a cleaner output of the traces and also enables the
    perf tool to use each tracepoint as a virtual performance counter,
    allowing us to e.g. count how often certain workloads git various
    spots in XFS. Take a look at

    http://lwn.net/Articles/346470/

    for some examples.

    Also the btree tracing isn't included at all yet, as it will require
    additional core tracing features not in mainline yet, I plan to
    deliver it later.

    And the really nice thing about this patch is that it actually removes
    many lines of code while adding this nice functionality:

  • 7d095257e   xfs: kill xfs_qmops ... Browse Code »

    Kill the quota ops function vector and replace it with direct calls or
    stubs in the CONFIG_XFS_QUOTA=n case.

    Make sure we check XFS_IS_QUOTA_RUNNING in the right spots. We can remove
    the number of those checks because the XFS_TRANS_DQ_DIRTY flag can't be set
    otherwise.

    This brings us back closer to the way this code worked in IRIX and earlier
    Linux versions, but we keep a lot of the more useful factoring of common
    code.

    Eventually we should also kill xfs_qm_bhv.c, but that's left for a later
    patch.

    Reduces the size of the source code by about 250 lines and the size of
    XFS module by about 1.5 kilobytes with quotas enabled:

    text data bss dec hex filename
    615957 2960 3848 622765 980ad fs/xfs/xfs.o
    617231 3152 3848 624231 98667 fs/xfs/xfs.o.old

    Fallout:

    - xfs_qm_dqattach is split into xfs_qm_dqattach_locked which expects
    the inode locked and xfs_qm_dqattach which does the locking around it,
    thus removing XFS_QMOPT_ILOCKED.

  • e6d29426b   [XFS] Fix uquota and oquota enforcement problems. ... Browse Code »

    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.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
