| |
Hello.
As was agreed[1][2], clone3 should fail if the provided exit_signal value fails valid_signal() check, hence the new version.
Changees since v2[3][4]: - Rewrite the check to check exit_signal against valid_signal().
Changes since v1[5]: - Check changed to comparison against negated CSIGNAL to address the bug reported by Oleg[6]. - Added a comment to _do_fork that exit_signal has to be checked by the caller.
