From b7a8d756fb8080ab6ba9f4a9d4056a1056245fbc Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Mon, 13 Oct 2014 15:54:42 -0700 Subject: [PATCH] batman-adv: 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.
