Hi zhanglianjie,

Shouldn't be TST_EXP_PID_SILENT()
Because TST_EXP_POSITIVE() prints extra TPASS which is useless:

clone01.c:31: TPASS: clone() returned 11556
clone01.c:37: TPASS: clone returned 11556
clone01.c:43: TPASS: Child exited with 0

but with TST_EXP_PID_SILENT():
clone01.c:37: TPASS: clone returned 11986
clone01.c:43: TPASS: Child exited with 0

and on deliberate error (using -1 as flag):
clone01.c:31: TFAIL: clone() failed: EINVAL (22)
clone01.c:34: TBROK: wait(0x7ffed515f3ec) failed: ECHILD (10)

	if (child_pid ==  TST_RET)

=> run `make check-clone01' to see this error (and run make check-* for other
tests).


Kind regards,

Hi,
Thank you I will resubmit.

Hi,
Please ignore other patches about clone testcases and just focus on 
v3.thanks.

Hi zhanglianjie,

FYI you can register on our patchwork instance [1] with email you use for
sending patches and update status of your patches (e.g. set patches to be
ignored to "Superseded" or "Changes Requested").

Kind regards,
Petr

FYI you'll be able to change state of your patches.
But in cases like this it helps us to handle the queue (we're always late).

Kind regards,
Petr
