Subject: [PATCH v2 0/2] Transaction abort macro optimizations
Date: Thu,  7 May 2026 19:59:30 +0200	[thread overview]
Message-ID: <cover.1778176579.git.dsterba@suse.com> (raw)

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()
