Description Florian Weimer 2021-12-16 20:12:30 UTC

criu does not know anything about rseq. glibc is going to enable rseq for sched_getcpu acceleration, so we need criu support for it, or criu will stop working completely.

rseq registration is a change to glibc's process startup, so all processes are impacted by this, not just processes using specific functions/system calls.
