    Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"),
    it has been basically impossible to build a kernel with CONFIG_HOTPLUG
    turned off. Remove all the remaining references to it.

    Fix build errors by correcting DLM dependencies in GFS2.

  • 6ecd7c2dd   gfs2: use workqueue instead of slow-work ... Browse Code »

    Workqueue can now handle high concurrency. Convert gfs to use
    workqueue instead of slow-work.

    * Steven pointed out that recovery path might be run from allocation
    path and thus requires forward progress guarantee without memory
    allocation. Create and use gfs_recovery_wq with rescuer. Please
    note that forward progress wasn't guaranteed with slow-work.

    * Updated to use non-reentrant workqueue.

  • fe64d517d   GFS2: Umount recovery race fix ... Browse Code »

    This patch fixes a race condition where we can receive recovery
    requests part way through processing a umount. This was causing
    problems since the recovery thread had already gone away.

    Looking in more detail at the recovery code, it was really trying
    to implement a slight variation on a work queue, and that happens to
    align nicely with the recently introduced slow-work subsystem. As a
    result I've updated the code to use slow-work, rather than its own home
    grown variety of work queue.

    When using the wait_on_bit() function, I noticed that the wait function
    that was supplied as an argument was appearing in the WCHAN field, so
    I've updated the function names in order to produce more meaningful
    output.

  • f057f6cdf   GFS2: Merge lock_dlm module into GFS2 ... Browse Code »

    This is the big patch that I've been working on for some time
    now. There are many reasons for wanting to make this change
    such as:
    o Reducing overhead by eliminating duplicated fields between structures
    o Simplifcation of the code (reduces the code size by a fair bit)
    o The locking interface is now the DLM interface itself as proposed
    some time ago.
    o Fewer lookups of glocks when processing replies from the DLM
    o Fewer memory allocations/deallocations for each glock
    o Scope to do further optimisations in the future (but this patch is
    more than big enough for now!)

    Please note that (a) this patch relates to the lock_dlm module and
    not the DLM itself, that is still a separate module; and (b) that
    we retain the ability to build GFS2 as a standalone single node
    filesystem with out requiring the DLM.

    This patch needs a lot of testing, hence my keeping it I restarted
    my -git tree after the last merge window. That way, this has the maximum
    exposure before its merged. This is (modulo a few minor bug fixes) the
    same patch that I've been posting on and off the the last three months
    and its passed a number of different tests so far.

  • 048bca223   [GFS2] No lock_nolock ... Browse Code »

    This patch merges the lock_nolock module into GFS2 itself. As well as removing
    some of the overhead of the module, it also means that its now impossible to
    build GFS2 without a lock module (which would be a pointless thing to do
    anyway).

    We also plan to merge lock_dlm into GFS2 in the future, but that is a more
    tricky task, and will therefore be a separate patch.

    We need to ensure that sector_t is 64bits for GFS2, so that we need to
    depend on LBD as well as LSF.

  • 77658aad2   [GFS2] Eliminate (almost) duplicate field from gfs2_inode ... Browse Code »

    The blocks counter is almost a duplicate of the i_blocks
    field in the VFS inode. The only difference is that i_blocks
    can be only 32bits long for 32bit arch without large single file
    support. Since GFS2 doesn't handle the non-large single file
    case (for 32 bit anyway) this adds a new config dependency on
    64BIT || LSF. This has always been the case, however we've never
    explicitly said so before.

    Even if we do add support for the non-LSF case, we will still
    not require this field to be duplicated since we will not be
    able to access oversized files anyway.

    So the net result of all this is that we shave 8 bytes from a gfs2_inode
    and get our config deps correct.

    This patch fixes a circular dependency by letting GFS2_FS_LOCKING_DLM
    and DLM depend on instead of select SYSFS.

    Since SYSFS depends on EMBEDDED this change shouldn't cause any problems
    for users.

    Since fs/dlm/lockspace.c and fs/gfs2/locking/dlm/sysfs.c use
    kernel_subsys, they should either DEPEND on it or SELECT it.
