Modified files: (Branch: RELENG_6)
sys/ufs/ffs ffs_snapshot.c ffs_vnops.c
Log:
MFC: Close a race when VOP_LOCK() on a snapshot file is attempted at the
same time as it is changed back into a normal file. The locker would
get the shared "snaplk" lock which would no longer be the correct lock
for the vnode.
