From eec013bbf66fd17fc5671de6744913cb68036a00 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 21 Oct 2021 13:40:32 +0200 Subject: s390/string: use generic strrchr Use generic strrchr instead of an optimized architecture specific variant. Performance of strrchr is not relevant for real life workloads, since the only user which may call this more frequently would be kbasename().
