Subject: [PATCH v2] scripts/recordmcount.c: account for .softirqentry.text
Date: Mon, 26 Sep 2016 17:10:26 +0200 [thread overview]
Message-ID: <1474902626-73468-1-git-send-email-dvyukov@google.com> (raw)
Commit "arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections"
added .softirqentry.text section, but it was not added to recordmcount.
So functions in the section are untracable.
Add the section to scripts/recordmcount.c and scripts/recordmcount.pl.
Fixes: be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections")
