Hi, this patchset puts together some followup fixes for the new KUnit test which were discussed on several locations.
1st patch: + adds a comment exaplaing why the test ignores pr_reserve() failures. + was proposed at https://lore.kernel.org/r/afuiqeskxjfig...@pathway.suse.cz + Thomas Weißschuh added into v4 of the original patch but I have already comitted v3 in the meantime, see https://lore.kernel.org/r/20250620-printk-ringbuffer-test-v4-1-8df873f1f...@linutronix.de 2nd patch: + dynamically allocates a cpu bitmap to make the code safe even on systems with many CPUs. + v1 was set by Arnd Bergmann but it had some problems, see https://lore.kernel.org/r/20250620192554.2234184-1-a...@kernel.org + This version just integreates the proposed fixes from https://lore.kernel.org/r/afkuqafn3bovs...@pathway.suse.cz 3rd patch: + stores "size" instead on "len" in struct prbtest_rbdata so that is can be used to check code sanity by __counted_by(size). + fixes https://lore.kernel.org/r/eaea66b9-266a-46e7-980d-33f40ad4b215@sabinyo.mountain + it is based on the idea from Thomas Weißschuh, see 20250626082605-c5fbbb88-f6cc-4659-bea0-a283cdb58...@linutronix.de Sigh, I should have asked people to send new patches. But this looked easier and I wanted to clean the table.
