[PATCH] vfs rerepost: fix RCU-lockdep false positive due to /proc
If a single-threaded process does a file-descriptor operation, and some other process accesses that same file descriptor via /proc, the current rcu_dereference_check_fdtable() can give a false-positive RCU-lockdep splat due to the reference count being increased by the /proc access after the reference-count check i... 24 Jun 2010 16:22

[PATCH 03/15] xattr: define vfs_getxattr_alloc and vfs_xattr_cmp
vfs_getxattr_alloc() and vfs_xattr_cmp() are two new kernel xattr helper functions. vfs_getxattr_alloc() first allocates memory for the requested xattr and then retrieves it. vfs_xattr_cmp() compares a given value with the contents of an extended attribute.
