  • Pull vfs pile (part one) from Al Viro:
    "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
    locking violations, etc.

    The most visible changes here are death of FS_REVAL_DOT (replaced with
    "has ->d_weak_revalidate()") and a new helper getting from struct file
    to inode. Some bits of preparation to xattr method interface changes.

    Misc patches by various people sent this cycle *and* ocfs2 fixes from
    several cycles ago that should've been upstream right then.

    PS: the next vfs pile will be xattr stuff."

  • Currently when 'range->start' is beyond the end of file system
    nothing is done and that fact is ignored, where in fact we should return
    EINVAL. The same problem is when 'range.len' is smaller than file system
    block.

    Fix this by adding check for such conditions and return EINVAL
    appropriately.

  • Pull vfs update from Al Viro:

    - big one - consolidation of descriptor-related logics; almost all of
    that is moved to fs/file.c

    (BTW, I'm seriously tempted to rename the result to fd.c. As it is,
    we have a situation when file_table.c is about handling of struct
    file and file.c is about handling of descriptor tables; the reasons
    are historical - file_table.c used to be about a static array of
    struct file we used to have way back).

    A lot of stray ends got cleaned up and converted to saner primitives,
    disgusting mess in android/binder.c is still disgusting, but at least
    doesn't poke so much in descriptor table guts anymore. A bunch of
    relatively minor races got fixed in process, plus an ext4 struct file
    leak.

    - related thing - fget_light() partially unuglified; see fdget() in
    there (and yes, it generates the code as good as we used to have).

    - also related - bits of Cyrill's procfs stuff that got entangled into
    that work; _not_ all of it, just the initial move to fs/proc/fd.c and
    switch of fdinfo to seq_file.

    - Alex's fs/coredump.c spiltoff - the same story, had been easier to
    take that commit than mess with conflicts. The rest is a separate
    pile, this was just a mechanical code movement.

    - a few misc patches all over the place. Not all for this cycle,
    there'll be more (and quite a few currently sit in akpm's tree)."

    Fix up trivial conflicts in the android binder driver, and some fairly
    simple conflicts due to two different changes to the sock_alloc_file()
    interface ("take descriptor handling from sock_alloc_file() to callers"
    vs "net: Providing protocol type via system.sockprotoname xattr of
    /proc/PID/fd entries" adding a dentry name to the socket)

  • There's no reason to call rcu_barrier() on every
    deactivate_locked_super(). We only need to make sure that all delayed rcu
    free inodes are flushed before we destroy related cache.

    Removing rcu_barrier() from deactivate_locked_super() affects some fast
    paths. E.g. on my machine exit_group() of a last process in IPC
    namespace takes 0.07538s. rcu_barrier() takes 0.05188s of that time.

  • - Pass the user namespace the uid and gid values in the xattr are stored
    in into posix_acl_from_xattr.

    - Pass the user namespace kuid and kgid values should be converted into
    when storing uid and gid values in an xattr in posix_acl_to_xattr.

    - Modify all callers of posix_acl_from_xattr and posix_acl_to_xattr to
    pass in &init_user_ns.

    In the short term this change is not strictly needed but it makes the
    code clearer. In the longer term this change is necessary to be able to
    mount filesystems outside of the initial user namespace that natively
    store posix acls in the linux xattr format.

  • Since the moment writes to quota files are using block device page cache and
    space for quota structures is reserved at the moment they are first accessed we
    have no reason to sync quota before inode writeback. In fact this order is now
    only harmful since quota information can easily change during inode writeback
    (either because conversion of delayed-allocated extents or simply because of
    allocation of new blocks for simple filesystems not using page_mkwrite).

    So move syncing of quota information after writeback of inodes into ->sync_fs
    method. This way we do not have to use ->quota_sync callback which is primarily
    intended for use by quotactl syscall anyway and we get rid of calling
    ->sync_fs() twice unnecessarily. We skip quota syncing for OCFS2 since it does
    proper quota journalling in all cases (unlike ext3, ext4, and reiserfs which
    also support legacy non-journalled quotas) and thus there are no dirty quota
    structures.

  • After we moved inode_sync_wait() from end_writeback() it doesn't make sense
    to call the function end_writeback() anymore. Rename it to clear_inode()
    which well says what the function really does - set I_CLEAR flag.

  • There is no reason to export two functions for entering the
    refrigerator. Calling refrigerator() instead of try_to_freeze()
    doesn't save anything noticeable or removes any race condition.

    * Rename refrigerator() to __refrigerator() and make it return bool
    indicating whether it scheduled out for freezing.

    * Update try_to_freeze() to return bool and relay the return value of
    __refrigerator() if freezing().

    * Convert all refrigerator() users to try_to_freeze().

    * Update documentation accordingly.

    * While at it, add might_sleep() to try_to_freeze().
