  • c4be0c1dc   filesystem freeze: add error handling of write_super_lockfs/unlockfs ... Browse Code »

    Currently, ext3 in mainline Linux doesn't have the freeze feature which
    suspends write requests. So, we cannot take a backup which keeps the
    filesystem's consistency with the storage device's features (snapshot and
    replication) while it is mounted.

    In many case, a commercial filesystem (e.g. VxFS) has the freeze feature
    and it would be used to get the consistent backup.

    If Linux's standard filesystem ext3 has the freeze feature, we can do it
    without a commercial filesystem.

    So I have implemented the ioctls of the freeze feature.
    I think we can take the consistent backup with the following steps.
    1. Freeze the filesystem with the freeze ioctl.
    2. Separate the replication volume or create the snapshot
    with the storage device's feature.
    3. Unfreeze the filesystem with the unfreeze ioctl.
    4. Take the backup from the separated replication volume
    or the snapshot.

    This patch:

    VFS:
    Changed the type of write_super_lockfs and unlockfs from "void"
    to "int" so that they can return an error.
    Rename write_super_lockfs and unlockfs of the super block operation
    freeze_fs and unfreeze_fs to avoid a confusion.

    ext3, ext4, xfs, gfs2, jfs:
    Changed the type of write_super_lockfs and unlockfs from "void"
    to "int" so that write_super_lockfs returns an error if needed,
    and unlockfs always returns 0.

    reiserfs:
    Changed the type of write_super_lockfs and unlockfs from "void"
    to "int" so that they always return 0 (success) to keep a current behavior.

  • 8f659adfa   CRED: Wrap task credential accesses in the JFS filesystem ... Browse Code »

    Wrap access to task credentials so that they can be separated more easily from
    the task_struct during the introduction of COW creds.

    Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

    Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more
    sense to use RCU directly rather than a convenient wrapper; these will be
    addressed by later patches.

  • a447c0932   vfs: Use const for kernel parser table ... Browse Code »

    This is a much better version of a previous patch to make the parser
    tables constant. Rather than changing the typedef, we put the "const" in
    all the various places where its required, allowing the __initconst
    exception for nfsroot which was the cause of the previous trouble.

    This was posted for review some time ago and I believe its been in -mm
    since then.

    * kill nameidata * argument; map the 3 bits in ->flags anybody cares

    * kill redundant gfs2_iop_permission()

    * fix remaining places where ->permission() instances might barf on new
    MAY_... found in mask.

    The obvious next target in that direction is permission(9)

    Kmem cache passed to constructor is only needed for constructors that are
    themselves multiplexeres. Nobody uses this "feature", nor does anybody uses
    passed kmem cache in non-trivial way, so pass only pointer to object.

    Non-trivial places are:

    arch/powerpc/mm/hugetlbpage.c

    This is flag day, yes.

    Move declarations of some macros, which should be in fact functions to

    because we can now use declarations from quota.h. Also add necessary

    Stop the JFS filesystem from using iget() and read_inode(). Replace
    jfs_read_inode() with jfs_iget(), and call that instead of iget(). jfs_iget()
    then uses iget_locked() directly and returns a proper error code instead of an
    inode in the event of an error.

    jfs_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

  • e47776a0a   Forbid user to change file flags on quota files ... Browse Code »

    Forbid user from changing file flags on quota files. User has no bussiness
    in playing with these flags when quota is on. Furthermore there is a
    remote possibility of deadlock due to a lock inversion between quota file's
    i_mutex and transaction's start (i_mutex for quota file is locked only when
    trasaction is started in quota operations) in ext3 and ext4.
