    CIFS: Introduce SMB2 Kconfig option · 675f36fb
    Steve French authored
    SMB2 is the followon to the CIFS (and SMB) protocols
    and the default for Windows since Windows Vista, and also
    now implemented by various non-Windows servers. SMB2
    is more secure, has various performance advantages, including
    larger i/o sizes, flow control, better caching model and more.
    SMB2 also resolves some scalability limits in the CIFS
    protocol and adds many new features while being much
    simpler (only a few dozen commands instead of hundreds)
    and since the protocol is clearer it is also more consistently
    implemented across servers and thus easier to optimize.
    
    After much discussion with Jeff Layton, Jeremy Allison
    and others at Connectathon, we decided to move the SMB2
    code from a distinct .ko and fstype into distinct
    C files that optionally build in cifs.ko. As a result
    the Kconfig gets simpler.
    
    To avoid destabilizing CIFS, the SMB2 code is going
    to be moved into its own experimental CONFIG_CIFS_SMB2 ifdef
    as it is merged and rereviewed. The changes to stable
    CIFS (builds with the SMB2 ifdef off) are expected to be
    fairly small.
