Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull SMB3 fixes from Steve French:
"A collection of CIFS/SMB3 fixes.
It includes a couple bug fixes, a few for improved debugging of
cifs.ko and some improvements to the way cifs does key generation.
I do have some additional bug fixes I expect in the next week or two
(to address a problem found by xfstest, and some fixes for SMB3.11
dialect, and a couple patches that just came in yesterday that I am
reviewing)"
* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
cifs_dbg() outputs an uninitialized buffer in cifs_readdir()
cifs: fix race between call_async() and reconnect()
Prepare for encryption support (first part). Add decryption and encryption key generation. Thanks to Metze for helping with this.
cifs: Allow using O_DIRECT with cache=loose
cifs: Make echo interval tunable
cifs: Check uniqueid for SMB2+ and return -ESTALE if necessary
Print IP address of unresponsive server
cifs: Ratelimit kernel log messages
