Re: [PATCH 2/2] KVM: selftests: Use getcpu() instead of sched_getcpu() in rseq_test

* Gavin Shan:

sched_getcpu() is glibc dependent and it can simply return the CPU ID from the registered rseq information, as Florian Weimer pointed. In this case, it's pointless to compare the return value from sched_getcpu() and that fetched from the registered rseq information.

Fix the issue by replacing sched_getcpu() with getcpu(), as Florian suggested. The comments are modified accordingly.

Note that getcpu was added in glibc 2.29, so perhaps you need to perform a direct system call?

Thanks, Florian
