Description Guenther Deschner 2018-05-31 10:43:14 UTC 
When deleting a file, all leases granting handle caching lease to the file should be recalled (as it is happening on Windows). In Samba this is not the case.

Searching MS-FSA for "2.1.4.12" (Algorithm to Check for an Oplock Break) it seems there's more missing, eg in

2.1.5.16 Server Requests Setting of Security Information

ie when a client sets a DACL we should check for H breaks.

We'll also need this for Directory Leases, looking...
