Subject: [PATCH 12/37] xfs: fix the wrong new_size/rnew_size at xfs_iext_realloc_direct()
Date: Wed,  6 Nov 2013 12:06:58 +1100	[thread overview]
Message-ID: <1383700043-32305-13-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1383700043-32305-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

At xfs_iext_realloc_direct(), the new_size is changed by adding
if_bytes if originally the extent records are stored at the inline
extent buffer, and we have to switch from it to a direct extent
list for those new allocated extents, this is wrong.

This patch fix above problem and revise the new_size comments at
xfs_iext_realloc_direct() to make it more readable.  Also, fix the
comments while switching from the inline extent buffer to a direct
extent list to reflect this change.

Ported from kernel commit 17ec81c1.
