[SSI] openssi/kernel/include/net af_unix.h,1.7,1.8

Update of /cvsroot/ssic-linux/openssi/kernel/include/net
In directory sfp-cvsdas-3.v30.ch3.sourceforge.com:/tmp/cvs-serv3340/include/net

Modified Files:
      Tag: OPENSSI-FC
	af_unix.h 
Log Message:
IPC (UNIX domain sockets):
- Implement lockless unixnm_svr_table list traversal. Reduce connect(), sendmsg() contention with bind(), connect(), sendmsg().
- ssi_unix_deregister() do O(1) lookup. Remove release() contention with bind() and various paths with unix_table_lock.
- unixnm_put() do O(1) lookup. Reduce release() contention with bind(), connect(), sendmsg().
- Allocate unixnm_svr_entry and unixnm_cache_entry structures from the Linux slab cache.
