[PATCH v2 0/2] Transaction abort macro optimizations

[David Sterba <dsterba@suse.com>]

Optimize size of the macro btrfs_abort_transaction() by encoding the
'first hit' logic into the error code. Additionally also verify that the
error code is negative.

v2:

- add patch with the verification
- in second patch reuse local variable for btrfs_abort_should_print_stack()

David Sterba (2):
  btrfs: validate negative error number passed to
    btrfs_abort_transaction()
  btrfs: simplify how first hit is passed to __btrfs_abort_transaction()
