linux-toradex.git/fs/coda, branch v3.7.2 Linux kernel for Apalis and Colibri modules fs: push rcu_barrier() from deactivate_locked_super() to filesystems 2012-10-03T01:35:55+00:00 Kirill A. Shutemov kirill.shutemov@linux.intel.com 2012-09-26T01:33:07+00:00 8c0a85377048b64c880e76ec7368904fe46d0b94 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. Signed-off-by: Kirill A.

Rename it to clear_inode() which well says what the function really does - set I_CLEAR flag. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Fengguang Wu <fengguang.wu@intel.com>
