For a second I thought ltp tests has `-f` option. So maybe if we can make it absolutely clear, or maybe it is just me. :D Reviewed-by: Avinesh Kumar <akumar@suse.de> > > Developers corner > ================= Thanks, Avinesh

There is currently no -f parameter, but sure, it could be in the future. ./fanotify01 -h # shows no -f parameter ./fanotify01 -f ... tst_test.c:688: TBROK: Invalid option But I meant '-f' as strace parameter, e.g.: strace -f ./fanotify01 should I wrote this? To trace test with strace use call strace with `-f` parameter. Kind regards, Petr
