Bug Description
[Impact]
Adding these changes will enable GDS functionality for NVMe and NVMeOF drivers.
[Fix]
This is a not a fix but a new feature being added to NVMe and NVMeOF driver.
[Test]
Tested the NVMe driver on a hpe system as I did not have a setup with BASEOS6.
1) Installed 5.15.39 kernel on the system (this is the kernel that optimized kernel is on currently).
2) Downloaded the optimized kernel.
3) Applied the patches to the optimized kernel
4) Replaced the nvme modules on the system with the one's built on optimized kernel.
5) Ran gds tests on ext4 file system with the patched NVMe driver. All tests went fine.
6) The boot drive is on NVMe and the system is up and running which indicates no regression on the standard NVMe path as well.
Attached are the results with NVMe
