[PATCH 4.14 24/89] timers: Unconditionally check deferrable base

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

commit ed4bbf7910b28ce3c691aef28d245585eaabda06 upstream.

When the timer base is checked for expired timers then the deferrable base
must be checked as well. This was missed when making the deferrable base
independent of base::nohz_active.

Fixes: ced6d5c11d3e ("timers: Use deferrable base independent of base::nohz_active")
