This patch extends CRIU with support for SCHED_RESET_ON_FORK. When the SCHED_RESET_ON_FORK flag is set, the following rules apply for subsequently created children: - If the calling thread has a scheduling policy of SCHED_FIFO or SCHED_RR, the policy is reset to SCHED_OTHER in child processes. - If the calling process has a negative nice value, the nice value is reset to zero in child processes. (See 'man 7 sched') Fixes: checkpoint-restore#2359 Signed-off-by: Radostin Stoyanov <rstoyanov@fedoraproject.org>
