Re: [PATCH] slab: fix kmalloc_nolock() context check for PREEMPT_RT

[Swaraj Gaikwad]

I agree that we can simplify this. I think !preemptible() would be
the most descriptive choice here, as it directly expresses the
constraint, we cannot take a sleeping lock when preemption is
disabled.
The updated check would be:
    if (IS_ENABLED(CONFIG_PREEMPT_RT) && !preemptible())

I'll send a v2 with this change unless there are objections.
