vfs: avoid call to inode_lru_list_del() if possible inode_lru_list_del() is expensive because of per superblock lru locking, while some inodes are not in lru list. Adding a check in iput_final() can speedup pipe/sockets workloads on SMP. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
