Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6

Pull CIFS fixes from Steve French:
 "A set of cifs cleanup fixes.

  The only big one of this set optimizes the cifs error logging,
  renaming cFYI and cERROR macros to cifs_dbg, and in the process makes
  it clearer and reduces module size."

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: small variable name cleanup
  CIFS: fix error return code in cifs_atomic_open()
  cifs: store the real expected sequence number in the mid
  cifs: on send failure, readjust server sequence number downward
  cifs: remove ENOSPC handling in smb_sendv
  [CIFS] cifs: Rename cERROR and cFYI to cifs_dbg
  fs: cifs: use kmemdup instead of kmalloc + memcpy
  cifs: replaced kmalloc + memset with kzalloc
  cifs: ignore the unc= and prefixpath= mount options
