[PATCH 0/12 V2] ipc: cleanups & bugfixes, rhashtable update

[Manfred Spraul]

Hi,

I have merged the patches from Dmitry, Davidlohr and myself:

- patch #1-#6: Fix syzcall findings & further race cleanups
- patch #7: Cleanup from Dmitry for ipc_idr_alloc.
- patch #8-#11: rhashtable improvement from Davidlohr
- patch #12: Another cleanup for ipc_idr_alloc.

@Davidlohr:
Please double check that I have taken the correct patches, and
that I didn't break anything.
Especially, I had to reformat the commit ids, otherwise checkpatch
complained.

@Dmitry: Patch #12 reworks your ipc_idr_alloc patch.
Ok?

@Andrew:
Can you merge the patches into -mm/next?

I have not seen any issues in my tests.
