[PATCH 0/1] sched/deadline: Log Fair Server re-enablement

Hi Ingo, Peter, Juri, Vincent,

During a recent audit of the Fair Server related code, I observed that
whilst disabling the server via the debugfs interface emits a console
notification, re-enabling it remains silent. This patch rectifies that
asymmetry by ensuring a corresponding message is logged when runtime is
restored.

This omission was identified during the investigation and code review
following the recent discussion regarding
SCHED_FEAT(RT_SUPPRESS_FAIR_SERVER) [1]. Please note that this patch is
standalone and does not depend upon the aforementioned RFC patch.
