From: Christoph Hellwig Date: Wed, 28 Apr 2010 12:28:53 +0000 (+0000) Subject: xfs: remove iomap_delta X-Git-Tag: v2.6.35-rc2~3^2^2~35 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9563b3d8998c78d5b7e718b546d5f68037c494fe;p=platform%2Fkernel%2Flinux-3.10.git xfs: remove iomap_delta The iomap_delta field in struct xfs_iomap just contains the difference between the offset passed to xfs_iomap and the iomap_offset. Just calculate it in the only caller that cares.
