>Subject: [PATCH] ctdb-locking: Reset real-time priority in lock helper
>
>BUG: https://bugzilla.samba.org/show_bug.cgi?id=12392
>
>Earlier we were relying on SCHED_RESET_ON_FORK to reset the priority of lock
>helper processes.  Since SCHED_RESET_ON_FORK support has been removed, the
>scheduling priority of child processes created using vfork() need to be reset
>explicitly in the helper processes.
