Re: fallocate can't change the cifs disk space usage

[Steve French <smfrench@gmail.com>]

I was looking in a little more detail at tests 213 and 228 ... and I
see 228 passing to all servers I tried.  Did you see a problem with
that?

With 213 I see it working to Windows, and to Samba test 213 also works
but only if "strict allocate = yes" is set in smb.conf (I just
verified it on the buildbot)
