Date: Tue, 16 Sep 2014 22:51:32 +0200 From: Rasmus Villemoes <linux@...musvillemoes.dk> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org, Rasmus Villemoes <linux@...musvillemoes.dk>, "Rafael J. Wysocki" <rafael.j.wysocki@...el.com> Subject: [PATCH 18/22] PNP: Replace strnicmp with strncasecmp The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g. Cc: "Rafael J.
