From: Namhyung Kim Date: Thu, 5 Dec 2024 23:15:29 +0000 (-0800) Subject: perf tools: Fix precise_ip fallback logic X-Git-Tag: v6.13-rc3~34^2~6 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=c33aea446bf555ab;p=linux-block.git perf tools: Fix precise_ip fallback logic Sometimes it returns other than EOPNOTSUPP for invalid precise_ip so it cannot check the error code. Let's move the fallback after the missing feature checks so that it can handle EINVAL as well. This also aligns well with the existing behavior which blindly turns off the precise_ip but we check the missing features correctly now.
