* [PATCH 15/22] Input: edt-ft5x06 - Replace strnicmp with strncasecmp [not found] <1410900696-6481-1-git-send-email-linux@rasmusvillemoes.dk> @ 2014-09-16 20:51 ` Rasmus Villemoes 2014-09-17 16:26 ` Dmitry Torokhov 0 siblings, 1 reply; 2+ messages in thread From: Rasmus Villemoes @ 2014-09-16 20:51 UTC (permalink / raw) To: Andrew Morton Cc: linux-kernel, Rasmus Villemoes, Dmitry Torokhov, linux-input 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.
