Based on a conversation with Volker, refactor some of the oplock code to make it comprehensible.
delay_for_oplocks() did 4 things. 1). Validation of existing oplock types. 2). Check for compatibility with batch oplocks (pass 1). 3). Check for compatibility with exclusive oplocks (pass 2). 4). Set the correct oplock type from the requested value. Refactor into 4 separate functions: 1). find_oplock_types() - does validation of oplock types and returns pointers to specific values. 2). delay_for_batch_oplocks() - the pass 1 phase above. 3). delay_for_exclusive_oplocks() - the pass 2 phase above 4). grant_fsp_oplock_type() - Set the correct oplock type from the requested value. Now separated out this code should be much easier to understand and modify. This also fixes an erroneous SMB_ASSERT which was hidden by the previous complexity of the single delay_for_oplocks() code.
