Hi

Can I ask as to the status of these patches? I found they stabilized
my RXE test environment a lot. I went from being unable to complete a
run of

ib_write_bw -a -b -d rxe1

due to stalling of network traffic to successful completion of the same
command across all packet sizes with only a stack depth warning of the
form:

[ 1315.810430] kworker/dying (14) used greatest stack depth: 12736 bytes left

So I would like to see some version of this patchset make it into the
codebase soon.

FYI my test configuration is a QEMU socket based network connection
between two QEMU instances running on a bare-metal machine. Running
4.8-rc6 with these three patches applied. For more information on my
test setup see the NVMf over Soft RoCE section of the README.md in [1].
