Subject: Btrfs: fix number of transaction units required to create symlink
From: Filipe Manana <fdmanana@xxxxxxxx>
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.
