Eric Dumazet 7123aaa3a1 af_unix: speedup /proc/net/unix ... /proc/net/unix has quadratic behavior, and can hold unix_table_lock for a while if high number of unix sockets are alive. (90 ms for 200k sockets...) We already have a hash table, so its quite easy to use it. Problem is unbound sockets are still hashed in a single hash slot (unix_socket_table[UNIX_HASH_TABLE]) This patch also spreads unbound sockets to 256 hash slots, to speedup both /proc/net/unix and unix_diag. Time to read /proc/net/unix with 200k unix sockets : (time dd if=/proc/net/unix of=/dev/null bs=4k) before : 520 secs after : 2 secs Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Steven Whitehouse <swhiteho@redhat.com> Cc: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.
