Subject[PATCH v2 00/10] Performance fixes for 9p filesystem
This is the second version of a patch series which adds a number
of features to improve read/write performance in the 9p filesystem.
Mostly it focuses on fixing caching to help utilize the recently
increased MSIZE limits and also fixes some problematic behavior
within the writeback code.

Altogether, these show roughly 10x speed increases on simple
file transfers. Future patch sets will improve cache consistency
and directory caching.

These patches are also available on github:

Tested against qemu, cpu, and diod with fsx, dbench, and some
simple benchmarks.
