Previously, using "%m" in a ksft_* format string can result in strange output because the errno value wasn't saved before calling other libc functions. The solution is to simply save and restore the errno before we format the user-supplied format string. Signed-off-by: Aleksa Sarai <redacted>[...] Hi Aleksa, Can you send this patch separate from the patch series. I will apply this as bug fix to 5.3-rc2 or rc3. This isn't part of this series anyway and I would like to get this in right away.
Done, and I'll drop it in v11 after the rest gets reviewed. -- Aleksa Sarai Senior Software Engineer (Containers) SUSE Linux GmbH <https://www.cyphar.com/>
