Hi,
Sorry to resurrect an old issue, but I've just come across the same (or
very similar-looking) problem. I'm also on an Openstack Swift storage
node with lots of small writes to SSDs as in the OP, running on Debian
Stretch in our case with the following kernel:
Linux swift-storage-1 4.9.0-6-amd
Closed as the kernel version is no longer in use

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.7 kernel[0
Hi Joseph,
we only stress tested from the beginning with a 4.4 kernel so I can not rule
out if the was introduced past 3.13 or persisted in earlier versions already.
I'll look if I can test this in a smaller scale with a 4.7 kernel, we can not
switch for 4.7 on our current system yet

FYI I have seen similar issues on 3.18 on a different OS so I assume
this issue is longer persistent than anticipated.
So far I was not able to reproduce in a test environment where I can try
different kernels.
Not sure how we should proceed here
