Glad this helps!

However, the version that I am pushing during the upcoming merge window
requires a boot parameter rcutree.kthread_prio= set to a value in the
range 1..99 to have effect.  The reason is that we need to focus any
risks from this change on the people needing it.

							Thanx, Paul

Glad this helps!

However, the version that I am pushing during the upcoming merge window
requires a boot parameter rcutree.kthread_prio= set to a value in the
range 1..99 to have effect.  The reason is that we need to focus any
risks from this change on the people needing it.

							Thanx, Paul
