[Crash-utility] HEADS UP: crash will fail to initialize with upstream CONFIG_SLAB kernels
Just a heads-up to those who may be running with bleeding-edge upstream
kernels that have this commit:

mm/slab: use percpu allocator for cpu cache
This change will cause the crash session to fail during initialization
if the target kernel is configured with CONFIG_SLAB. I haven't tried
it, but it looks like it would fail with an invalid structure member
offset message w/respect to "kmem_cache_s_array". To work around it,
you could try using the --no_kmem_cache command line option.
Since RHEL and Fedora use CONFIG_SLUB, it wouldn't be an issue with
those distributions.
