https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v3.2.682011-05-27T00:12:38Zbitops: add #ifndef for each of find bitops2011-05-27T00:12:38ZAkinobu Mitaakinobu.mita@gmail.com2011-05-26T23:26:09Zurn:sha1:19de85ef574c3a2182e3ccad9581805052f14946
The style that we normally use in asm-generic is to test the macro itself
for existence, so in asm-generic, do:
#ifndef find_next_zero_bit_le
extern unsigned long find_next_zero_bit_le(const void *addr,
unsigned long size, unsigned long offset);
#endif
and in the architectures, write
static inline unsigned long find_next_zero_bit_le(const void *addr,
unsigned long size, unsigned long offset)
#define find_next_zero_bit_le find_next_zero_bit_le
This adds the #ifndef for each of the find bitops in the generic header
and source files.

Impact: New API
As the name suggests. For the moment everyone uses the generic one.
