[MS-FSCC] specifies:
The number of FILE_ALLOCATED_RANGE_BUFFER elements returned is
computed by dividing the size of the returned output buffer (from
either SMB or SMB2, the lower-layer protocol that carries the FSCTL)
by the size of the FILE_ALLOCATED_RANGE_BUFFER element.
Ideally, this requirement could be defined in idl with the following:
[flag(NDR_REMAINING)] file_alloced_range_buf array[];
However, this is not currently supported by PIDL, so just use an opaque
data blob for now.

This test finds the minimum length at which a zeroed range in a sparse

It also checks whether zeroed neighbours are merged for deallocation.

Depends on new share "dynamic_share" being set up containing an %R
in the path= statement.
Shows we will break leases and fail to grant new ones
if we get a lease_key+client guid pair match on files
with different fileid's, as can happen on dynamic shares.

This demonstrates a race case where the client reuses a lease,
while the server already sent a break.
The open succeeds with SMB2_LEASE_FLAG_BREAK_IN_PROGRESS being set.
This is more complex that smb2.lease.breaking[1-2] as it generates breaks
from RWH => RH => R => NONE.

They demonstrate that the lease version (v1 or v2) is selected
by the first open. All following opens using the other version
still get the lease version of the first open.
This implies that the server has to remember the lease version
more globaly.

Attempt to punch holes in a file using FSCTL_SET_ZERO_DATA. Check that
the resulting data is zeroed. Also confirm that when the file is marked
sparse, the zeroed range is no longer allocated.
Finally, check that removing the sparse flag causes any holes to be
unsparsed.
