In reply to: Daniel Latypov: "[PATCH v3 5/6] kunit: split out part of kunit_assert into a static const"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

This field has been split out from kunit_assert to make the struct less
heavy along with the filename and line number.

This change drops the assert_type field and cleans up all the macros
that were plumbing assert_type into kunit_assert.
