[Bug 192734] Re: lsof got can't stat() tmpfs file system errors

[elatllat]

I can reliably reproduce this issue by restarting the remote service or server.
1) cifs should recover but instead is unusable until remount and starts flooding the server (other file systems have a errors=remount-ro option; cifs would benefit from a errors=remount option)
2) lsof should somehow list that cifs is attempting to use the mount


lsof | grep ws
lsof: WARNING: can't stat() cifs file system /media/ws
      Output information may be incomplete.
