    Subject[patch 06/69] reiserfs: suppress lockdep warning
    -stable review patch.  If anyone has any objections, please let us know.
    ---------------------

    From: Jeff Mahoney <jeffm@suse.de>

    We're getting lockdep warnings due to a post-2.6.21-rc7 bugfix.

    The xattr_sem can never be taken in the manner described. Internal inodes
    are protected by I_PRIVATE. Add the appropriate annotation.
