From 7fb1cab4ac8ef7a1fed5c19593cd5b4be1b1a9b3 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Mon, 13 Oct 2014 15:54:54 -0700 Subject: 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. Signed-off-by: Rasmus Villemoes Cc: "Rafael J.
