6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Henrique Carvalho <henrique.carvalho@xxxxxxxx>
[ Upstream commit ceaf1451990e3ea7fb50aebb5a149f57945f6e9f ]
Setting dir_cache_timeout to zero should disable the caching of
directory contents. Currently, even when dir_cache_timeout is zero,
some caching related functions are still invoked, which is unintended
behavior.
Fix the issue by setting tcon->nohandlecache to true when
dir_cache_timeout is zero, ensuring that directory handle caching
is properly disabled.
Fixes: 238b351d0935 ("smb3: allow controlling length of time directory entries are cached with dir leases")
