gfs2: fix quota updates on block boundaries
For smaller block sizes (512B, 1K, 2K), some quotas straddle block boundaries such that the usage value is on one block and the rest of the quota is on the previous block. In such cases, the value does not get updated correctly. This patch fixes that by addressing the boundary conditions correctly. This patch also adds a (s64) cast that was missing in a call to gfs2_quota_change() in inode.c Signed-off-by: NAbhi Das <adas@redhat.com> Signed-off-by: NBob Peterson <rpeterso@redhat.com>
