Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma fixes from Jason Gunthorpe:
"Over the break a few defects were found, so this is a -rc style pull
request of various small things that have been posted.
- An attempt to shorten RCU grace period driven delays showed crashes
during heavier testing, and has been entirely reverted
- A missed merge/rebase error between the advise_mr and ib_device_ops
series
- Some small static analysis driven fixes from Julia and Aditya
- Missed ability to create a XRC_INI in the devx verbs interop
series"
