History
Michael Niewöhner 6d948c3519 Add kmem_cache flag for forcing kvmalloc 
This adds a new KMC_KVMEM flag was added to enforce use of the
kvmalloc allocator in kmem_cache_create even for large blocks, which
may also increase performance in some specific cases (e.g. zstd), too.

Default to KVMEM instead of VMEM in spl_kmem_cache_create.
