Log:
SVN rev 181429 on 2008-08-08 14:36:21Z by rwatson
Merge r177843,178147 from head to stable/7:
Add rw_try_rlock() and rw_try_wlock() to rwlocks.
These functions try the specified operation (rlocking and wlocking) and
true is returned if the operation completes, false otherwise.
The KPI is enriched by this commit, so __FreeBSD_version bumping and
manpage updating will happen soon.
Requested by: jeff, kris
Trylocks were implemented, remove stale comment
Discussed with: attilio, jhb
