Hi all,
After merging the bitmap tree, today's linux-next build (native powerpcle
perf) failed like this:
../lib/bitmap.c:21:5: error: conflicting types for '__bitmap_weight_cmp'; have 'int(const long unsigned int *, unsigned int, int)'
21 | int __bitmap_weight_cmp(const unsigned long *bitmap, unsigned int bits, int num)
| ^~~~~~~~~~~~~~~~~~~
In file included from ../lib/bitmap.c:6:
tools/include/linux/bitmap.h:15:5: note: previous declaration of '__bitmap_weight_cmp' with type 'int(const long unsigned int *, unsigned int, unsigned int)'
15 | int __bitmap_weight_cmp(const unsigned long *bitmap, unsigned int bits,
| ^~~~~~~~~~~~~~~~~~~
../lib/bitmap.c: In function '__bitmap_weight_cmp':
