(Garrett I was going to add your ack, but wasn't absolutely sure whether you meant it should apply to the whole thing or not)
Most of these are belated cleanup after the move to using /opt/ltp. But come on, replacing 'return' with tst_exit(), are you just trying to mess with my head? Changelog: may 4: address Garrett's feedback 1. single return 0 in print_caps.c 2. use $TMP if defined for location of caps_fifo 3. use tst_brkm in place of tst_resm. may 5: address Garrett's comment: don't add 1 to null pointer and then check for 1 Signed-off-by: Serge E.
