Re: [PATCH V1 22/26] migration: ram block cpr-exec blockers

Add an exec-mode blocker for volatile ram blocks. Also add a blocker for RAM_GUEST_MEMFD. Preserving guest_memfd may be sufficient for cpr-exec, but it has not been tested yet. - Steve extra text here Will fix, thanks - steve Signed-off-by: Steve Sistare Reviewed-by: Fabiano Rosas
