NP, in these cases please resend the affected patch with a v2 in the
subject line, i.e.:

Subject: [PATCH 2/3 v2] perf: introduce errno_to_name() function

Some other issues with that subject line, please check the differences:

Subject: [PATCH 2/3 v2] perf trace: Introduce errno_to_name()

Regards,
