  smb: client: fix potential UAF in cifs_signal_cifsd_for_reconnect()
(2024-04-03 14:45:15 -0500)

----------------------------------------------------------------
17 cifs.ko changesets, most also for stable
- fix to retry close to avoid potential handle leaks when server returns EBUSY
- Three DFS fixes including a fix for potential use after free
- fscache fix
- minor strncpy cleanup
- reconnect race fix
- series of patches to deal with various possible race conditions
(UAFs) tearing sessions down

The important fix to support password rotation is not included in this P/R (am
giving that patch more time for any additional review feedback) but should be
ready to send next week.
