SUNRPC: Clean up the sillyrename code
Fix a couple of bugs: - Don't rely on the parent dentry still being valid when the call completes. Fixes a race with shrink_dcache_for_umount_subtree() - Don't remove the file if the filehandle has been labelled as stale. Fix a couple of inefficiencies - Remove the global list of sillyrenamed files. Instead we can cache the sillyrename information in the dentry->d_fsdata - Move common code from unlink_setup/unlink_done into fs/nfs/unlink.c Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
