Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull CIFS fixes from Steve French:
"This is a set of CIFS/SMB3 fixes for stable.
There is another set of four SMB3 reconnect fixes for stable in
progress but they are still being reviewed/tested, so didn't want to
wait any longer to send these five below"
* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
Reset TreeId to zero on SMB2 TREE_CONNECT
CIFS: Fix build failure with smb2
Introduce cifs_copy_file_range()
SMB3: Rename clone_range to copychunk_range
Handle mismatched open calls
