Title:
  dmesg CIFS VFS: src file seems to be from a different filesystem type
  for every file i copy/move to shared folder

Status in linux package in Ubuntu:
  New
Status in samba package in Ubuntu:
  Incomplete

Bug description:
  #BASIC SETUP
  -server side: ext4 / lubuntu 14.04.5 / 4.4.0-72-generic #93~14.04.1-Ubuntu SMP .. i686 / samba 4.3.11
  -client side: ext4 / lubuntu 14.04.5 / 4.4.0-75-generic #96~14.04.1-Ubuntu SMP x86_64 / mount.cifs 6.0
  -both server and client are up-to-date
  -mount line: mount.cifs //ip/share /mountpoint -o username=user,password=pass,uid=buntu,gid=buntu

  #ANTERIOR WORKINGS PRIOR TO UPGRADES
  -the server worked fine prior to upgrading
  -the server had about 6 months prior to last upgrade (3 days ago)
  -the client had about 1 month prior to last upgrade (3 days ago)

  #THE PROBLEM
  -the "CIFS VFS: src file seems to be from a different filesystem type" appears inside dmesg for every file copy/move to server
  -the problem does not appear on connect with pcmanfm like smb://ip/share into the address bar
  -the problem does not appear on create,move,copy files through the mount straight on server

  #OTHER 
  -ive tested within virtualbox lubuntu 64 14.04.5 clean no upgrades apt-get install samba cifs-utils with the same problem
  -the copied/moved files seem do be fine.. checksum tested

  #EXPECTED RESULT
  -no error messages(ive read about lost files)
  -a clean workaround if possible(trough mount.cifs or samba options)
