Re: [PATCH v3 5/7] nvme-pci: add device coredump infrastructure

[Christoph Hellwig]

Usage of a scatterlist here is rather bogus as we never use
it for dma mapping.  Why can't you store the various pages in a
large bio_vec and then just issue that to the device in one
get log page command?  (or at least a few if MDTS kicks in?)
