Subject: [Xen-devel] [PATCH v2 23/48] xen/sched: switch sched_move_irqs() to take sched_unit as parameter
Date: Fri,  9 Aug 2019 16:58:08 +0200
Message-ID: <20190809145833.1020-24-jgross@suse.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>

sched_move_irqs() should work on a sched_unit as that is the unit
moved between cpus.

Rename the current function to vcpu_move_irqs() as it is still needed
in schedule().
