From 5048efee33592c421d860f55eea9d7782e1ef930 Mon Sep 17 00:00:00 2001 From: Henrique Carvalho Date: Fri, 22 Nov 2024 22:14:35 -0300 Subject: [PATCH] smb: client: disable directory caching when dir_cache_timeout is zero [ 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.
