Modified files:
sys/ufs/ufs ufs_vnops.c
Log:
Change UFS from using vop_stdlock to using its own ufs_lock.
In ufs_lock, check for attempts to acquire shared locks on
snapshot files and change them to be exclusive locks. This
change eliminates deadlocks and machine lockups reported in
-current since most read requests started using shared lock
requests.
