[PATCH 0/5] btrfs: fix exploits that allow malicious users to turn fs into RO mode

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

We have a couple scenarios that regular users can exploit to trigger a
transaction abort and turn a filesystem into RO mode, causing some
disruption. The first 2 patches fix these, the remainder are just a few
trivial and cleanups.

Filipe Manana (5):
  btrfs: fix transaction abort on file creation due to name hash collision
  btrfs: fix transaction abort when snapshotting received subvolumes
  btrfs: stop checking for -EEXIST return value from btrfs_uuid_tree_add()
  btrfs: remove duplicated uuid tree existence check in btrfs_uuid_tree_add()
  btrfs: remove pointless error check in btrfs_check_dir_item_collision()
