Commit Message

Steve French March 26, 2022, 9:26 p.m. UTC 
An additional patch this patch includes moving to common code (from
cifs and ksmbd protocol related headers)
    - query and query directory info levels and structs
    - set info structs
    - SMB2 lock struct and flags
    - SMB2 echo req

Also shorten a few flag names (e.g. SMB2_LOCKFLAG_EXCLUSIVE_LOCK to
SMB2_LOCKFLAG_EXCLUSIVE)

See attached
