From 2d5f4b5bebccfe983715ebc9255151e611234643 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 27 Nov 2017 09:50:22 -0800 Subject: [PATCH] xfs: remove unused parameter from xfs_writepage_map The first thing that xfs_writepage_map does is clobber the offset parameter. Since we never use the passed-in value, turn the parameter into a local variable. This gets rid of an UBSAN warning in generic/466. Signed-off-by: Darrick J.
