Merge tag '5.6-rc4-smb3-fixes' of git://git.samba.org/sfrench/cifs-2.6

Pull cifs fixes from Steve French:
 "Five small cifs/smb3 fixes, two for stable (one for a reconnect
  problem and the other fixes a use case when renaming an open file)"

* tag '5.6-rc4-smb3-fixes' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: Use #define in cifs_dbg
  cifs: fix rename() by ensuring source handle opened with DELETE bit
  cifs: add missing mount option to /proc/mounts
  cifs: fix potential mismatch of UNC paths
  cifs: don't leak -EAGAIN for stat() during reconnect
