[PATCH 0/3] btrfs: fixes for the received subvol ioctl

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

Fix a bug that can be exploited by malicious users to trigger a transaction
abort and turn the filesystem to RO mode by assigning the same received UUID
to a bunch of subvolumes, plus a missing transaction abort if we fail to
update a root item, and a cleanup.

Filipe Manana (3):
  btrfs: fix transaction abort on set received ioctl due to item overflow
  btrfs: abort transaction on failure to update root in the received subvol ioctl
  btrfs: remove unnecessary transaction abort in the received subvol ioctl
