[patch added to 3.12-stable] libxfs: clean up _calc_dquots_per_chunk

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Darrick J. Wong" <darrick.wong@xxxxxxxxxx>

This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.

===============

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.
