Currently with directory leases we cache directory contents for a fixed period of time (default 30 seconds) but for many workloads this is too short. Allow configuring the maximum amount of time directory entries are cached when a directory lease is held on that directory. Add module load parm "max_dir_cache" For example to set the timeout to 10 minutes you would do: echo 600 > /sys/module/cifs/parameters/dir_cache_timeout or to disable caching directory contents: echo 0 > /sys/module/cifs/parameters/dir_cache_timeout Reviewed-by: Bharath SM <bharathsm@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
