Subject: [PATCH] libxfs: clean up _calc_dquots_per_chunk
Date: Tue, 18 Oct 2016 16:35:54 -0700	[thread overview]
Message-ID: <20161018233554.GD20337@birch.djwong.org> (raw)

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.
