  • c1844d536   fs: Remove SB_I_DYNBDI flag ... Browse Code »

    Now that all bdi structures filesystems use are properly refcounted, we
    can remove the SB_I_DYNBDI flag.

  • fa06052d6   mtd: Convert to dynamically allocated bdi infrastructure ... Browse Code »

    MTD already allocates backing_dev_info dynamically. Convert it to use
    generic infrastructure for this including proper refcounting. We drop
    mtd->backing_dev_info as its only use was to pass mtd_bdi pointer from
    one file into another and if we wanted to keep that in a clean way, we'd
    have to make mtd hold and drop bdi reference as needed which seems
    pointless for passing one global pointer...

    Pass mount flags to sget() so that it can use them in initialising a new
    superblock before the set function is called. They could also be passed to the
    compare function.

  • 289c05222   mtd: replace DEBUG() with pr_debug() ... Browse Code »

    Start moving away from the MTD_DEBUG_LEVEL messages. The dynamic
    debugging feature is a generic kernel feature that provides more
    flexibility.

    (See Documentation/dynamic-debug-howto.txt)

    Also fix some punctuation, indentation, and capitalization that went
    along with the affected lines.

  • 6de940025   Fix JFFS2 sync silent failure ... Browse Code »

    JFFS2 does not appear to set s_bdi anywhere. And as of 32a88aa1,
    __sync_filesystem() will return 0 if s_bdi is not set. As a result,
    sync_fs() is never called for jffs2 and whatever remains in the wbuf
    will not make it to the device.

    Fix that up by assigning the mtd bdi.

  • a3ec947c8   vfs: simple_set_mnt() should return void ... Browse Code »

    simple_set_mnt() is defined as returning 'int' but always returns 0.
    Callers assume simple_set_mnt() never fails and don't properly cleanup if
    it were to _ever_ fail. For instance, get_sb_single() and get_sb_nodev()
    should:

    up_write(sb->s_unmount);
    deactivate_super(sb);

    if simple_set_mnt() fails.

    Since simple_set_mnt() never fails, would be cleaner if it did not
    return anything.

    As reported by Adrian Bunk, commit d5686b444ff3f72808d2b3fbd58672a86cdf38e7
    (switch mtd and dm-table to lookup_bdev()) causes the following compile
    error with CONFIG_BLOCK=n:

    CC drivers/mtd/mtdsuper.o
    drivers/mtd/mtdsuper.c: In function `get_sb_mtd':

    drivers/mtd/mtdsuper.c:197: error: implicit declaration of function 'bdput'
    make[3]: *** [drivers/mtd/mtdsuper.o] Error 1

    Fix it by putting the block device lookup inside #ifdef CONFIG_BLOCK

  • 4ac913785   Embed a struct path into struct nameidata instead of nd->{dentry,mnt} ... Browse Code »

    This is the central patch of a cleanup series. In most cases there is no good
    reason why someone would want to use a dentry for itself. This series reflects
    that fact and embeds a struct path into nameidata.

    Together with the other patches of this series
    - it enforced the correct order of getting/releasing the reference count on
    pairs
    - it prepares the VFS for stacking support since it is essential to have a
    struct path in every place where the stack can be traversed
    - it reduces the overall code size:

    without patch series:
    text data bss dec hex filename
    5321639 858418 715768 6895825 6938d1 vmlinux

    with patch series:
    text data bss dec hex filename
    5320026 858418 715768 6894212 693284 vmlinux

    This patch:

    Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
