From f9a196ee5ab517deff40ae57195416c13c44c13f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 12 Jun 2019 08:59:59 -0700 Subject: xfs: merge xfs_buf_zero and xfs_buf_iomove xfs_buf_zero is the only caller of xfs_buf_iomove. Remove support for copying from or to the buffer in xfs_buf_iomove and merge the two functions. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Chinner Reviewed-by: Darrick J.
