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

Pull CIFS fixes from Steve French:
 "Three cifs/smb3 fixes - including two for stable"

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: don't check for failure from mempool_alloc()
  Do not return number of bytes written for ioctl CIFS_IOC_COPYCHUNK_FILE
  Fix match_prepath()
