From d852a6afd91fc928128f59ebff381838c365e358 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Wed, 29 Sep 2010 18:08:51 +0900 Subject: bitops: remove duplicated extern declarations If CONFIG_GENERIC_FIND_NEXT_BIT is enabled, find_next_bit() and find_next_zero_bit() are doubly declared in asm-generic/bitops/find.h and linux/bitops.h. asm/bitops.h includes asm-generic/bitops/find.h if and only if the architecture enables CONFIG_GENERIC_FIND_NEXT_BIT. And asm/bitops.h is included by linux/bitops.h So we can just remove the extern declarations of find_next_bit() and find_next_zero_bit() in linux/bitops.h. Also we can remove unneeded #ifndef CONFIG_GENERIC_FIND_NEXT_BIT in asm-generic/bitops/find.h.
