Reason for closing:  Upstream
Additional comments about closing:  Old and stale. Plus it's clearly an upstream issue. If still happening with latest kernels, please follow up with upstream.

The system is using nfs? Have you reported it on the upstream linux-nfs mailing list?

Yes, it is an NFS client.

Same problem here, without NFS, but as a samba client.

@yodaz can you contact upstream using
linux-cachefs@redhat.com (moderated list:FS-CACHE: LOCAL CACHING FOR NETWORK FILESYSTEMS)
linux-kernel@vger.kernel.org (open list)
Comment by D.T. (MountainX) - Saturday, 23 June 2018, 16:04 GMT
There is an upstream bug report here: https://bugzilla.kernel.org/show_bug.cgi?id=200145

I suggest adding comments there or using the mailing lists @loqs provided above. I do not believe that comments here will have any value. (Correct me if I'm wrong.)

As has been pointed out on the upstream bug report this may well be working as intended https://bugzilla.kernel.org/show_bug.cgi?id=200145#c12
