Thanks for proposing this! I think this backport has the problem I was concerned with when Cliff Liu proposed a backport in March [1].

The handling of the 'has_lease' field in this patch depends on work done by two other patches, and those should be backported before this one:

• 5c86919455c1 ("smb: client: fix use-after-free in

smb2_query_info_compound()")

• 7afb86733685 ("smb: Don't leak cfid when reconnect races with

open_cached_dir")

I have (somewhere...) a backport of all three of these patches three patches to linux-6.1.y, but it was a while ago and I never found the time to _test_ the backports.

Now dropped from the queue, thanks for the review.
