[PATCH 0/3] Few transaction semantic fixes

[Nikolay Borisov <nborisov@suse.com>]

While looking at the transaction code and various pattern I came across some
problems which this series aim to fix. 

Patch 1 just removes some redundant code. 

Patch 2 adds a missing btrfs_abort_transaction, otherwise we don't properly 
close out the transaction. I believe this could lead to btrfs_root_item being 
modified yet we could be missing respective entry in the uuid tree. 

Patch 3 btrfs_rm_dev_item totally missed aborting the transaction in its failure
cases.

Nikolay Borisov (3):
  btrfs: Remove unnecessary btrfs_abort_transaction on transaction
    commit failure
  btrfs: Handle failure to add received uuid to uuid tree in 
  _btrfs_ioctl_set_received_subvol
  btrfs: Fix transaction abort during failure in btrfs_rm_dev_item
