From 1a36f2df9a8cc61a62b3cb1628e115592b51aa6f Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 10 Sep 2009 23:13:28 +0200 Subject: [PATCH] md: Fix "strchr" [drivers/md/dm-log-userspace.ko] undefined! Commit 4cdbf55aad23b84778385db62f1abdb381008ccb ("dm log: remove incorrect field from userspace table output") added a call to strstr() with a single-character "needle" string parameter. Unfortunately some versions of gcc replace such calls to strstr() by calls to strchr() behind our back. This causes linking errors if strchr() is defined as an inline function in (e.g. on m68k): | WARNING: "strchr" [drivers/md/dm-log-userspace.ko] undefined! Avoid this by explicitly calling strchr() instead.
