4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>
commit 58d789678546d46d7bbd809dd7dab417c0f23655 upstream.
The function xfs_calc_dquots_per_chunk takes a parameter in units
of basic blocks. The kernel seems to get the units wrong, but
userspace got 'fixed' by commenting out the unnecessary conversion.
Fix both.
