- Try to keep snapshot indirect blocks contiguous. This speeds up snapshot
creation by a factor of ~3 and reduces the file system suspension time by
a factor of ~5.
- Refine the scope of WAPBL transactions and the limit for deallocations in
one transaction so we should no longer get a "wapbl_flush: current
transaction too big to flush" panic when creating or removing snapshots
on larger logging disks.
- fss(4): Allow FSSIOCSET to set the initial flags. Add a new flag
"FSS_UNLINK_ON_CREATE" to unlink the backing store before the snapshot
gets created. With this change dump(8) no longer dumps the zero-sized,
but named snapshot it is working on.
