* Finish removing the custom 9p request cache mechanism
* Embed part of the fcall in the request to have better slab
performance (msize usually is power of two aligned)
* syzkaller fixes:
- add a refcount to 9p requests to avoid use after free
- a few double free issues
* A few coverity fixes
* Some old patches that were in the bugzilla:
- do not trust pdu content for size header
- mount option for lock retry interval

Merge tag '9p-for-4.20' of git://github.com/martinetd/linux
Pull 9p updates from Dominique Martinet:
"Highlights this time around are the end of Matthew's work to remove
the custom 9p request cache and use a slab directly for requests, with
some extra patches on my end to not degrade performance, but it's a
very good cleanup.
Tomas and I fixed a few more syzkaller bugs (refcount is the big one),
and I had a go at the coverity bugs and at some of the bugzilla
reports we had open for a while.
I'm a bit disappointed that I couldn't get much reviews for a few of
my own patches, but the big ones got some and it's all been soaking in
linux-next for quite a while so I think it should be OK.
Summary:
- Finish removing the custom 9p request cache mechanism
- Embed part of the fcall in the request to have better slab
performance (msize usually is power of two aligned)
- syzkaller fixes:
* add a refcount to 9p requests to avoid use after free
* a few double free issues
- A few coverity fixes
- Some old patches that were in the bugzilla:
* do not trust pdu content for size header
* mount option for lock retry interval"
