[why] Explain the meaning of new key "kernel_version" for scheduler, including what's the mapping between its typical values and actual files in the disk and how to set it.

+Related files: +- In initramfs boot process, every kernel version is related with a vmlinuz, module and headers. +- File paths like below, An example $boot_dir can be "/srv/os/openeuler/aarch64/20.03/boot"
+- $boot_dir/vmlinuz => $boot_dir/vmlinuz-$kernel_version
- default kernel file(vmlinuz) is a soft link
+- $boot_dir/modules => $boot_dir/modules-$kernel_version.cgz
- default modules is a soft link
+- $boot_dir/headers => $boot_dir/headers-$kernel_version.cgz
- default headers is a soft link
+- $boot_dir/vmlinuz-$kernel_version
- real kernel path
+- $boot_dir/modules-$kernel_version.cgz
- real modules path
+- $boot_dir/headers-$kernel_version.cgz
- real headers path
The above example looks a bit complex. This can be more simple:
wfg@crystal /srv/os/openeuler/aarch64/20.03/boot% tree|g 4.19.90-2003|g -v oe1 ├── headers-4.19.90-2003.cgz ├── headers.cgz -> headers-4.19.90-2003.cgz ├── modules-4.19.90-2003.cgz ├── modules.cgz -> modules-4.19.90-2003.cgz ├── vmlinuz-4.19.90-2003
btw, here the vmlinuz symlink does not match headers.cgz and modules.cgz
+Usage example: +- submit iperf.yaml testbox=vm-hi1620-2p8g--xxj os=openeuler os_arch=aarch64 os_version=20.03 runtime=20 kernel_version=4.19.90-2003
That example cannot be run by others (testbox too specific). Do you have a more general example?
Thanks, Fengguang

Oh yes, Thanks for reminding.
