sys/ufs/ffs ffs_vnops.c
sys/ufs/ufs ufs_vnops.c
Log:
For snapshots we need all VOP_LOCKs to be exclusive.
The "business class upgrade" was implemented in UFS's VOP_LOCK
implementation ufs_lock() which is the wrong layer, so move it to
ffs_lock().
Also, as long as we have not abandonned advanced vfs-stacking we
should not preclude it from happening: instead of implementing a
copy locally, use the VOP_LOCK_APV(&ufs) to correctly arrive at
vop_stdlock() at the bottom.
