Date: Fri, 4 Mar 2016 10:02:02 +0100 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Filipe Manana <fdmanana@...e.com>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 077/116] Btrfs: fix number of transaction units required to create symlink From: Filipe Manana <fdmanana@...e.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 9269d12b2d57d9e3d13036bb750762d1110d425c upstream. We weren't accounting for the insertion of an inline extent item for the symlink inode nor that we need to update the parent inode item (through the call to btrfs_add_nondir()). So fix this by including two more transaction units.
