From 09fb99a696412ae0fceeafc06c987903416503b9 Mon Sep 17 00:00:00 2001 From: Filipe David Borba Manana Date: Mon, 5 Aug 2013 16:25:12 +0100 Subject: [PATCH] Btrfs: return ENOSPC when target space is full In extent-tree.c:do_chunk_alloc(), early on we returned 0 (success) when the target space was full and when chunk allocation is needed. However, later on in that same function we return ENOSPC if btrfs_alloc_chunk() fails (and chunk allocation was needed) and set the space's full flag. This was inconsistent, as -ENOSPC should be returned if the space is full and a chunk allocation needs to performed. If the space is full but no chunk allocation is needed, just return 0 (success).
