kernel/tcmu-runner: fix uio_poll crash during uio device removal
Last modified: 2017-09-19 06:40:52 EDT
Having discussed it with Prasanna, it will be difficult to hit this code path with the fix for uio_read() not yet in.
Hence, will be verifying this bug only after bz 1473162 is fixed.
This issue is not seen at CNS (builds above cns-deploy-5.0.0-38.el7rhgs.x86_64). i.e., tcmu-runner-1.2.0-14.el7rhgs.x86_64
Logging and metrics using gluster block in ocp environment is up for close to 4 week now without any issues.

Please ignore this comment. This comment was not meant for this bug.
Tested and verified this on the build tcmu-runner-1.2.0-15 and gluster-block-0.2.1-13 and gluster-3.8.4-44
Multiple block creates and deletes were given in parallel and in a sequence from different peer nodes, on a 2*3 volume. No crash (mentioned in description) was seen, this time or multiple other times that block deletes have been executed.
Moving this to verified in rhgs 3.3.0.
