commit b5bf1733d6a391c4e90ea8f8468d83023be74a2a upstream.
For cases where implicit fall through case labels are intended,
to let us inform that to gcc >= 7:
CC /tmp/build/perf/util/string.o
util/string.c: In function 'perf_atoll':
util/string.c:22:7: error: this statement may fall through [-Werror=implicit-fallthrough=]
if (*p)
^
util/string.c:24:3: note: here
case '\0':
^~~~
So we introduce:
#define __fallthrough __attribute__ ((fallthrough))
And use it in such cases.
