| |
-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.
