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
