From dbf7fab09e9e0612a23ec7fee9570663b21fdfc9 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Thu, 31 Dec 2015 18:16:29 +0000 Subject: [PATCH] Btrfs: fix number of transaction units required to create symlink 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.
