Subject: [PATCH] cifs: log warning message (once) if out of disk space
commit d6fd41905ec577851734623fb905b1763801f5ef upstream.
We ran into a confusing problem where an application wasn't checking
return code on close and so user didn't realize that the application
ran out of disk space. log a warning message (once) in these
cases. For example:
[ 8407.391909] Out of space writing to \\oleg-server\small-share
