Merge branch 'for-linus' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs fixes from Steve French:
"Most important fixes in this set include three SMB3 fixes for stable
(including fix for possible kernel oops), and a workaround to allow
writes to Mac servers (only cifs dialect, not more current SMB2.1,
worked to Mac servers). Also fallocate support added, and lease fix
from Jeff"
* 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
[SMB3] Enable fallocate -z support for SMB3 mounts
enable fallocate punch hole ("fallocate -p") for SMB3
Incorrect error returned on setting file compressed on SMB2
CIFS: Fix wrong directory attributes after rename
CIFS: Fix SMB2 readdir error handling
[CIFS] Possible null ptr deref in SMB2_tcon
[CIFS] Workaround MacOS server problem with SMB2.1 write response
cifs: handle lease F_UNLCK requests properly
Cleanup sparse file support by creating worker function for it
Add sparse file support to SMB2/SMB3 mounts
Add missing definitions for CIFS File System Attributes
cifs: remove unused function cifs_oplock_break_wait
