| H A D | inet_connection_sock.c | 3c689b73 Wed Oct 08 16:18:04 CDT 2008 Eric Dumazet <dada1@cosmosbay.com> inet: cleanup of local_port_range
I noticed sysctl_local_port_range[] and its associated seqlock
sysctl_local_port_range_lock were on separate cache lines.
Moreover, sysctl_local_port_range[] was close to unrelated
variables, highly modified, leading to cache misses.
Moving these two variables in a structure can help data
locality and moving this structure to read_mostly section
helps sharing of this data among cpus.
Cleanup of extern declarations (moved in include file where
they belong), and use of inet_get_local_port_range()
accessor instead of direct access to ports values.
