Merge tag 'v7.2-rc1-smb3-server-fixes' of git://git.samba.org/ksmbd

Pull smb server fixes from Steve French:

 - Fix several use-after-free races in durable handle reconnect,
   supersede, and oplock handling

 - Avoid holding the inode oplock lock while waiting for a lease break
   acknowledgement. This removes delays of up to 35 seconds when cifs.ko
   closes a deferred handle in response to a lease break

 - Fix malformed security descriptor handling, including an undersized
   DACL allocation issue and an out-of-bounds ACE SID read

 - Fix memory leaks in security descriptor and DOS attribute xattr
   encoding/decoding error paths

 - Fix outstanding SMB2 credit leaks on aborted requests and correct the
   QUERY_INFO credit charge calculation

 - Fix hard-link creation without replacement being incorrectly rejected
   when the handle lacks DELETE access

 - Avoid unnecessary zeroing of large SMB2 read buffers

 - Add an oplock list lockdep annotation and update the documented
   support status for durable handles and SMB3.1.1 compression

 - Durable handle fixes to address ownership and lifetime races during
   reconnect, session teardown, oplock handling, and superseding opens,
   preventing stale session and file references from being used by
   concurrent operations
