From c44f649e281e93689827a206653696be9599a320 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Thu, 9 Oct 2014 21:15:44 +0100 Subject: [PATCH] Btrfs: make inode.c:compress_file_range() return void Its return value is useless, its single caller ignores it and can't do anything with it anyway, since it's a workqueue task and not the task calling filemap_fdatawrite_range (writepages) nor filemap_fdatawait_range(). Failure is communicated to such functions via start and end of writeback with the respective pages tagged with an error and AS_EIO flag set in the inode's imapping.
