X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fc9ef2978d440162f507f70cbc351006af9a77d4;p=thirdparty%2Fkernel%2Flinux.git

mm/kmemleak: remove unreachable return statement in scan_should_stop()

Patch series "mm/kmemleak: Improve scan_should_stop() implementation".

This series improves the scan_should_stop() function by addressing code
quality issues and enhancing kernel thread detection robustness.


This patch (of 2):

Remove unreachable "return 0;" statement as all execution paths return
before reaching it.

No functional change.
