Message

Matthew Sakai March 1, 2024, 4:38 a.m. UTC

Clean up code to consistently return and check for appropriate
return values, usually VDO_SUCCESS.

Matthew Sakai (2):
  dm vdo errors: remove unused error codes
  dm vdo indexer: update ASSERT and ASSERT_LOG_ONLY usage

Mike Snitzer (8):
  dm vdo memory-alloc: return VDO_SUCCESS on success
  dm vdo: check for VDO_SUCCESS return value from memory-alloc functions
  dm vdo int-map: return VDO_SUCCESS on success
  dm vdo thread-utils: return VDO_SUCCESS on vdo_create_thread success
  dm-vdo funnel-workqueue: return VDO_SUCCESS from
    make_simple_work_queue
  dm vdo permassert: audit all of ASSERT to test for VDO_SUCCESS
  dm vdo encodings: update some stale comments
  dm vdo target: eliminate inappropriate uses of UDS_SUCCESS
