From 894b36e35ae01186b77b083f3f67569a349062a6 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Mon, 7 Mar 2016 16:56:22 -0800 Subject: [PATCH] Btrfs: cleanup error handling in extent_write_cached_pages Now that we bail out immediately if ->writepage() returns an error, we don't need an extra error to retain the error code.
