Description

While testing Linux Target SCSI, LIO, with a Ceph File System file backstore, that is kernel mounted, I am seeing this warning on my LIO export gateway out of dmesg -T:

In the 12 hours since I started the ESXi test, I have seen this message in dmesg about 20 times.

I am using Ubuntu Trusty, the 4.4rc4 kernel and ceph 9.2.0 from http://ceph.com/debian-infernalis/
ceph -v
ceph version 9.2.0 (bb2ecea240f3a1d525bcb35670cb07bd1f0ca299)
uname -a
Linux dfgw01 4.4.0-040400rc4-generic #201512061930 SMP Mon Dec 7 00:32:31 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Additional information can be found in the dev mail list:
http://article.gmane.org/gmane.comp.file-systems.ceph.devel/28664

The exported file is 900GB, to be less then the 1TB default max size of a Ceph File System file.

I have attached the output of dmesg -T
