Hi all,
this is the tip of the iceberg of some of the PI work I've done a while
ago, and given the current discussions it might be a good time to send it
out.
The idea is to:
a) make the auto-PI code stand out more clearly as it seems to lead to
a lot of confusion
b) optimize the size of the integrity payload to prepare for usage in
file systems
c) make sure the mempool backing actually works for auto-PI. We'll still
need a mempool for the actual metadata buffer, but that is left for the
next series.
Changes since RFC
- rename the auto-pi source file
- fix a typo in a printk message
