sys/kern sysv_msg.c
Log:
Make SYSVMSG mpsafe. Right now there is a global lock over the
entire subsystem, we could move to per-message queue locks, however
the messages themselves seem to come from a global pool and to avoid
over-locking this code (locking individual queues, then the global
pool) I've opted to just do it this way.
Requested by: rwatson
Tested by: NetBSD's regression suite.
