Subject[RFC PATCH 0/4] rseq: Introduce extensible struct rseq
Date
Recent discussion led to a solution for extending struct rseq. This is
an implementation of the proposed solution.

Now is a good time to agree on this scheme before the release of glibc
2.32, just in case there are small details to fix on the user-space
side in order to allow extending struct rseq.

Thanks,

Mathieu

selftests: rseq: Use fixed value as rseq_len parameter
rseq: Allow extending struct rseq
selftests: rseq: define __rseq_abi with extensible size
selftests: rseq: print rseq extensible size in basic test
