__always_inline can cause build error on musl libc. The fix patch has submitted but not merged yet[1]. To build perf tool with musl libc, <linux/stddef.h> inclusion is necessary and it should be included before perf_event.h.
from /usr/include/linux/byteorder/little_endian.h:13, from /usr/include/asm/byteorder.h:23, from tools/include/uapi/linux/perf_event.h:20, from arch/arm64/util/../../arm/util/pmu.c:9:
/usr/include/linux/swab.h:171:8: error: unknown type name '__always_inline' 171 | static __always_inline __u16 __swab16p(const __u16 *p) | ^~~~~~~~~~~~~~~
