Eric Dumazet 88b3f3dc89 vfs: dont chain pipe/anon/socket on superblock s_inodes list 
Workloads using pipes and sockets hit inode_sb_list_lock contention.

superblock s_inodes list is needed for quota, dirty, pagecache and
fsnotify management. pipe/anon/socket fs are clearly not candidates for
these.
