[PATCH v2 02/22] bitops: rename generic little-endian bitops functions

From: Akinobu Mita
Date: Thu Oct 21 2010 - 10:43:07 EST

Next message: Akinobu Mita: "[PATCH v2 03/22] s390: introduce little-endian bitops"
Previous message: Akinobu Mita: "[PATCH v2 01/22] bitops: merge little and big endian definisions in asm-generic/bitops/le.h"
Next in thread: Arnd Bergmann: "Re: [PATCH v2 02/22] bitops: rename generic little-endian bitops functions"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

As a preparation for providing little-endian bitops for all architectures,
This removes generic_ prefix from little-endian bitops function names
in asm-generic/bitops/le.h.
