Comment 33 for bug 2009325

I have sent a patch to fix the upstream error (https://lkml.org/lkml/2023/3/8/107),
which is intended to resolve the issue of a massive increase in ACCESS operations.
I have also prepared a test kernel that includes this patch and would appreciate it if you could use it for testing.

To install the test kernel, please follow these steps:

1. Run the following command: sudo add-apt-repository ppa:chengendu/jammy-nfs-patch
2. Update the packages: sudo apt update
3. Install the kernel packages: sudo apt install linux-headers-5.15.0-67-generic linux-image-unsigned-5.15.0-67-generic linux-modules-5.15.0-67-generic linux-modules-extra-5.15.0-67-generic
4. Reboot your system.
5. To check the installed kernel version, run the command 'uname -rv', which should output '5.15.0-67-generic #74+test20230308b0h1a13a615ee32-Ubuntu SMP Wed Mar 8 09:24:49 UT'.
