From 8ad7c629b18695ec1ee8654fb27599864049862b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 28 Aug 2017 10:21:04 -0700 Subject: [PATCH] xfs: remove the ip argument to xfs_defer_finish And instead require callers to explicitly join the inode using xfs_defer_ijoin. Also consolidate the defer error handling in a few places using a goto label. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
