persistent handles

Persistent handles appear here in the context of SMB3 continuous availability, specifically Samba 4.25's experimental support for SMB3 Persistent Handles on SMB-exclusive shares. The tagged discussion explains how Windows and other SMB3 clients can reconnect after a Linux file-server restart or outage while still holding valid handles to open files, a capability aimed at workloads such as VM storage and clustered databases rather than ordinary file servers. It also notes the trade-offs, including added latency on open, update, lease and close operations, plus related Samba 4.25 changes such as AES becoming the default Kerberos encryption for many Samba AD domains.
