Hi! > +/*\ > + * [Description] > + * This is a test for the clone(2) system call. > + * It is intended to provide a limited exposure of the system call.

You can easily check for these with the checkpatch.pl script as described in: https://github.com/linux-test-project/ltp/wiki/Test-Writing-Guidelines#6-test-contribution-checklist > -static int do_child(void) > -{ > - exit(0); > -} > +static struct tst_test test = { > + .setup = setup, > + .cleanup = cleanup, > + .test_all = verify_clone, > + .forks_child = 1, > +// .needs_tmpdir = 1, If it's not needed just delete the line, no commented code please. > +}; > \ No newline at end of file > -- > 2.20.1 > > > > > -- > Mailing list info: https://lists.linux.it/listinfo/ltp
