perf beauty: Move copy of fadvise.h from tools/include/ to tools/perf/trace/beauty/include/
As it is not really used when compiling anything, just being parsed to collect number->string tables for 'perf trace'. $ git grep fadvise.h tools/ tools/perf/Makefile.perf:$(fadvise_advice_array): $(beauty_uapi_linux_dir)/fadvise.h $(fadvise_advice_tbl) tools/perf/check-headers.sh: "include/uapi/linux/fadvise.h" tools/perf/trace/beauty/fadvise.sh:grep -E $regex ${header_dir}/fadvise.h | \ tools/perf/trace/beauty/fadvise.sh:# tools/include/uapi/linux/fadvise.h for details. $ Link: https://lore.kernel.org/r/CAP-5=fVBNQVF8k3JUQjH1nkP69ZVp8BqP+uwygcx=xO0zC4xrg@mail.gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org>
