Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull CIFS fixes from Steve French: "CIFS update including case insensitive file name matching improvements for UTF-8 to Unicode, various small cifs fixes, SMB2/SMB3 leasing improvements, support for following SMB2 symlinks, SMB3 packet signing improvements" * 'for-next' of git://git.samba.org/sfrench/cifs-2.6: (25 commits) CIFS: Respect epoch value from create lease context v2 CIFS: Add create lease v2 context for SMB3 CIFS: Move parsing lease buffer to ops struct CIFS: Move creating lease buffer to ops struct CIFS: Store lease state itself rather than a mapped oplock value CIFS: Replace clientCanCache* bools with an integer [CIFS] quiet sparse compile warning cifs: Start using per session key for smb2/3 for signature generation cifs: Add a variable specific to NTLMSSP for key exchange. cifs: Process post session setup code in respective dialect functions. CIFS: convert to use le32_add_cpu() CIFS: Fix missing lease break CIFS: Fix a memory leak when a lease break comes cifs: add winucase_convert.pl to Documentation/ directory cifs: convert case-insensitive dentry ops to use new case conversion routines cifs: add new case-insensitive conversion routines that are based on wchar_t's [CIFS] Add Scott to list of cifs contributors cifs: Move and expand MAX_SERVER_SIZE definition cifs: Expand max share name length to 256 cifs: Move string length definitions to uapi ...
