commit 2d510bcb1402d0af81000cb5eb1f6bcf7cb29d59
Author: QuzarDC <qu...@co...>
Date: Tue Aug 5 16:19:40 2025 -0400
arch: Update to `__pure2` on `kos_get_{banner,license,authors}`
This maps to the gcc function attribute `const` which is stricter
than pure in that it guarantees it will have no observable effect
other than to return a value and the value will not change.
commit d8e3229c13744def2876206ffa68a7effbb699b1
Author: QuzarDC <qu...@co...>
Date: Tue Aug 5 14:50:50 2025 -0400
mutex: Add `__pure` to `mutex_is_locked` prototype.
This got lost when rebasing changes in #992 to take into
account the changes in #1047 .
