Re: [PATCH v2] nvmet-tcp: Don't kmap() pages which can't come from HIGHMEM

[Christoph Hellwig]

This introduced tons of pointless over 80 character lines, please stick
to a proper coding style.

Also or in-kernel I/O wouldn't it make more sense to use a BVEC iter
insted of a KVEC if we have the pages anyway?  Or does networking not
support them properly?
