> This Jira is to use bit manipulation, instead of hashmap in OzoneManager lock 
> logic. And also this Jira follows the locking order based on the document 
> attached to HDDS-1672 jira.
> This Jira is created based on [~anu] comment during review of HDDS-1672.
> Not a suggestion for this patch. But more of a question, should we just 
> maintain a bitset here, and just flip that bit up and down to see if the lock 
> is held. Or we can just maintain 32 bit integer, and we can easily find if a 
> lock is held by Xoring with the correct mask. I feel that might be super 
> efficient. [@nandakumar131|https://github.com/nandakumar131] . But as I said 
> let us not do that in this patch.
>  
> This Jira will add new class, integration of this new class into code will be 
> done in a new jira. 
> Clean up of old code also will be done in new jira.
