Subject: [PATCH 0/2] A couple of sched_getattr() fixes for DL

Hi all,

In the context of [1] it became apparent that the way __getparam_dl()
copies the sched_flags into the dl_entity struct for deadline tasks can
have undesirable side effects. This series fixes two issues in that area
causing sched_getattr() to report stale values or things it shouldn't
report to userspace.

Thanks,
Quentin
