When connecting to SMB2/3 shares, maximum file size is set to non-LFS maximum in superblock. This is due to cap_large_files bit being different for
SMB1 and SMB2/3 (where it is just an internal flag that is not negotiated and the SMB1 one corresponds to multichannel capability) while capabilities
are checked always for the SMB1 bit in cifs_read_super().
The patch fixes this by checking for the correct bit according to the protocol version.
Sorry for the repost, GMail messed up my previous mail (and I even confirmed it on the mailing list!), sorry!
