Porting notes:
- ZoL currently does not log discards to zvols, so the portion of
this patch that modifies the discard logging to mark it as
freeing space has been discarded.
2. may_delete_now had been removed from zfs_remove() in ZoL.
It has been reintroduced.
3. We do not try to emulate vnodes, so the following lines are
not valid on Linux:
mutex_enter(&vp->v_lock);
may_delete_now = vp->v_count == 1 && !vn_has_cached_data(vp);
mutex_exit(&vp->v_lock);
This has been replaced with:
mutex_enter(&zp->z_lock);
may_delete_now = atomic_read(&ip->i_count) == 1 && !(zp->z_is_mapped);
mutex_exit(&zp->z_lock);
