free disk space bug in 2.2

[Patrick Scharrenberg]

Hi..

okay.. I now corrected the quota value so that it's real 10 Gig
(10x1024x1024x1024).
because it was only a test I used the 10*1000*1000*1000..

okay.. the user is using 256 k of his disk-space
Samba reports:
10.737.418.240 byte of total space
and
10.737.156.096 byte of free space

but the free disk space on this fs is:
   5.688.381.440

so the value that samba returns IS wrong.
