RT-Kernel boot stalls because of change in fs/dcache.c

Hi,

I have tried to boot a 4.14-Kernel with the RT-patches and
PREEMPT_RT_FULL on an i.MX6UL board. Unfortunately the boot stalls at
some point and never finishes.

I did some bisecting and found out, that reverting this change: [1],
makes the board boot correctly.

Can anyone help to come up with a proper fix for this?

Thanks,
Frieder
