Subject: [patch 18/47] generic minix_{test,set,test_and_clear,test,find_first_zero}_bit()
Date: Tue, 14 Feb 2006 05:04:09 +0000 [thread overview]
Message-ID: <20060214050445.212426000@localhost.localdomain> (raw)
In-Reply-To: 20060214050351.252615000@localhost.localdomain
This patch introduces the C-language equivalents of the functions below:
int minix_test_and_set_bit(int nr, volatile unsigned long *addr);
int minix_set_bit(int nr, volatile unsigned long *addr);
int minix_test_and_clear_bit(int nr, volatile unsigned long *addr);
int minix_test_bit(int nr, const volatile unsigned long *addr);
unsigned long minix_find_first_zero_bit(const unsigned long *addr,
unsigned long size);
In include/asm-generic/bitops/minix.h
and include/asm-generic/bitops/minix-le.h
This code largely copied from:
include/asm-sparc/bitops.h
