bitmap_alloc() is defined as an inline function in
tools/include/linux/bitmap.h (since 4.8), which is included as a part
of this patch. Do you mind double-checking if you have it in the
header file?
Also, the function is referenced by other tests such as
dirty_log_[perf_]]test.c. Do you see the same warnings when you
compile them too?
Regards,
Raghavendra
