Re: [REGRESSION] "split bio_kmalloc from bio_alloc_bioset" causing crash shortly after bootup

[Christoph Hellwig]

The problem is that the blk-crypto fallback code calls bio_split
with a NULL bioset.  That was aready broken before, as the mempool
needed to guarantee forward progress was missing, but is not fatal.

Satya, can you look into adding a mempool that can guarantees forward
progress here?
