perf probe: Do not use map_load filters for function
It is simpler to just do the loop, no need for globals and the last user of such facility disappears. Testing: # perf probe -F [a-z]*recvmsg aead_recvmsg compat_SyS_recvmsg compat_sys_recvmsg hash_recvmsg inet_recvmsg kernel_recvmsg netlink_recvmsg packet_recvmsg ping_recvmsg raw_recvmsg rawv6_recvmsg rng_recvmsg security_socket_recvmsg selinux_socket_recvmsg skcipher_recvmsg sock_common_recvmsg sock_no_recvmsg sock_recvmsg sys_recvmsg tcp_recvmsg udp_recvmsg udpv6_recvmsg unix_dgram_recvmsg unix_seqpacket_recvmsg unix_stream_recvmsg # Without filters: # perf probe -F | tail -5 zswap_pool_create zswap_pool_current zswap_update_total_size zswap_writeback_entry zswap_zpool_param_set # # perf probe -F | wc -l 33311 # Acked-by: Masami Hiramatsu <mhiramat@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/20160831130427.GA13095@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
