Arnaldo Carvalho de Melo 16cab3226f Revert "perf bench futex: Sanitize numeric parameters" ... This reverts commit 60758d6668. Now that libsubcmd makes sure that OPT_UINTEGER options will not return negative values, we can revert this patch while addressing the problem it solved: # perf bench futex hash -t -4 # Running 'futex/hash' benchmark: Error: switch `t' expects an unsigned numerical value Usage: perf bench futex hash <options> -t, --threads <n> Specify amount of threads # perf bench futex hash -t-4 # Running 'futex/hash' benchmark: Error: switch `t' expects an unsigned numerical value Usage: perf bench futex hash <options> -t, --threads <n> Specify amount of threads # IMO it is more reasonable to flat out refuse to process a negative number than to silently turn it into an absolute value. This also helps in silencing clang's complaint about asking for an absolute value of an unsigned integer: bench/futex-hash.c:133:10: error: taking the absolute value of unsigned type 'unsigned int' has no effect [-Werror,-Wabsolute-value] nsecs = futexbench_sanitize_numeric(nsecs); ^ bench/futex.h:104:42: note: expanded from macro 'futexbench_sanitize_numeric' #define futexbench_sanitize_numeric(__n) abs((__n)) ^ bench/futex-hash.c:133:10: note: remove the call to 'abs' since unsigned values cannot be negative Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Davidlohr Bueso <dbueso@suse.de> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Josh Poimboeuf <jpoimboe@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-2kl68v22or31vw643m2exz8x@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2017-02-14 15:19:17 -03:00
