    * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: (57 commits)
    tidy the trailing symlinks traversal up
    Turn resolution of trailing symlinks iterative everywhere
    simplify link_path_walk() tail
    Make trailing symlink resolution in path_lookupat() iterative
    update nd->inode in __do_follow_link() instead of after do_follow_link()

    readlinkat(), fchownat() and fstatat() with empty relative pathnames
    Allow O_PATH for symlinks
    New kind of open files - "location only".
    ext4: Copy fs UUID to superblock
    ext3: Copy fs UUID to superblock.
    vfs: Export file system uuid via /proc//mountinfo
    unistd.h: Add new syscalls numbers to asm-generic
    x86: Add new syscalls for x86_64
    x86: Add new syscalls for x86_32
    fs: Remove i_nlink check from file system link callback

  • c83ce989c   VFS: Fix the nfs sillyrename regression in kernel 2.6.38 ... Browse Code »

    The new vfs locking scheme introduced in 2.6.38 breaks NFS sillyrename
    because the latter relies on being able to determine the parent
    directory of the dentry in the ->iput() callback in order to send the
    appropriate unlink rpc call.

    Looking at the code that cares about races with dput(), there doesn't
    seem to be anything that specifically uses d_parent as a test for
    whether or not there is a race:
    - __d_lookup_rcu(), __d_lookup() all test for d_hashed() after d_parent
    - shrink_dcache_for_umount() is safe since nothing else can rearrange
    the dentries in that super block.
    - have_submount(), select_parent() and d_genocide() can test for a
    deletion if we set the DCACHE_DISCONNECTED flag when the dentry
    is removed from the parent's d_subdirs list.

  • c826cb7df   dcache.c: create helper function for duplicated functionality ... Browse Code »

    This creates a helper function for he "try to ascend into the parent
    directory" case, which was written out in triplicate before. With all
    the locking and subtle sequence number stuff, we really don't want to
    duplicate that kind of code.

  • c1e8d35ef   ocfs2: Remove EXIT from masklog. ... Browse Code »

    mlog_exit is used to record the exit status of a function.
    But because it is added in so many functions, if we enable it,
    the system logs get filled up quickly and cause too much I/O.
    So actually no one can open it for a production system or even
    for a test.

    This patch just try to remove it or change it. So:
    1. if all the error paths already use mlog_errno, it is just removed.
    Otherwise, it will be replaced by mlog_errno.
    2. if it is used to print some return value, it is replaced with
    mlog(0,...).
    mlog_exit_ptr is changed to mlog(0.
    All those mlog(0,...) will be replaced with trace events later.

  • b4e1b7e88   ocfs2: Make the left masklogs compat. ... Browse Code »

    Since we have removed almost all of the masklogs in fs/ocfs2/*,
    make the left masklogs compat.

  • 6218b90e7   ocfs2: Little refactoring against ocfs2_iget. ... Browse Code »

    ocfs2_iget is used to get/create inode. Only iget5_locked
    will give us an inode = NULL. So move this check ahead of
    ocfs2_read_locked_inode so that we don't need to check
    inode before we read and unlock inode. This is also helpful
    for trace event(see the next patch).

  • da561c9cf   ocfs2: remove INODE from unused files. ... Browse Code »

    As there are no such debug information in fs/ocfs2/ioctl.c,
    fs/ocfs2/locks.c and fs/ocfs2/sysfile.c, ML_INODE are also
    removed.

  • 80a9a84da   ocfs2: Add ocfs2_trace.h. ... Browse Code »

    About one year ago, Wengang Wang tried some first steps
    to add tracepoints to ocfs2. Hiss original patch is here:
    http://oss.oracle.com/pipermail/ocfs2-devel/2009-November/005512.html

    But as Steven Rostedt indicated in his article
    http://lwn.net/Articles/383362/, we'd better have our trace
    files resides in fs/ocfs2, so I rewrited the patch using the
    method Steven mentioned in that article.

  • ef6b689b6   ocfs2: Remove ENTRY from masklog. ... Browse Code »

    ENTRY is used to record the entry of a function.
    But because it is added in so many functions, if we enable it,
    the system logs get filled up quickly and cause too much I/O.
    So actually no one can open it for a production system or even
    for a test.

    So for mlog_entry_void, we just remove it.
    for mlog_entry(...), we replace it with mlog(0,...), and they
    will be replace by trace event later.
