Dave opines:
IMO, there is no need to do this unnecessary work on every object
that is added to the LRU. Changing the gc worker to always run
every 2s and check if it has work to do like so:
static void
nfsd_file_gc_worker(struct work_struct *work)
{
- nfsd_file_gc();
- if (list_lru_count(&nfsd_file_lru))
- nfsd_file_schedule_laundrette();
+ if (list_lru_count(&nfsd_file_lru))
+ nfsd_file_gc();
+ nfsd_file_schedule_laundrette();
}
means that nfsd_file_gc() will be run the same way and have the same
behaviour as the current code. When the system it idle, it does a
list_lru_count() check every 2 seconds and goes back to sleep.
That's going to be pretty much unnoticable on most machines that run
NFS servers.

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 reStructuredText 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.
