perf trace: Show error message when not finding a field used in a filter expression
It was there, but as pr_debug(), make it pr_err() so that we can see it without -v: # trace -e syscalls:*lseek --filter="whenc==SET" sleep 1 "whenc" not found in "syscalls:sys_enter_lseek", can't set filter "whenc==SET" # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-ly4rgm1bto8uwc2itpaixjob@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
