[BUG] More an I need help building for 5.14.0 kernel

[4nanook]

Bug description

Describe the issue, or paste the full error encountered here.

I am trying to build for kernel 5.14.0 but it fails. I suspect the issue is not knowing what to put in to the release tag in order to get the proper version for this kernel.

How to reproduce

What are the steps to reproduce the reported issue.

git clone https://github.com/snuf/iomemory-vsl.git
cd iomemory-vsl
git checkout <tag or some-branch>
make module
** poof, broken token **

Possible solution

Is a solution know, or type any plausible suggestions here, if none leave clear.

Environment information

Information about the system the module is used on

1. Linux kernel compiled against (uname -a)

2. The C compiler version used (gcc --version)

3. distribution, and version (cat /etc/os-release)

4. Tag or Branch of iomemory-vsl that is being compiled I do not know the correct tag to put in for 5.14.0 kernel. I can see there was a commit for this four days ago but I am not very familiar with git and do not know how to pull the code with this applied.

5. FIO device used, if applicable

   • fio-status
   • lspci -b -nn

5.14 is not "released" yet. The code is in main (what you checkout by default), does compile/work/run and was tested on ubuntu 21.04 with 5.14-rc6.

I do not know what to specify for as given in these instructions:

Releases

Releases are tagged, and should be checked out by their tag. The release tags fo llow Linux Kernel versions. E.g. v5.12.1 (A Fine Boi) will work on all 5.x k ernels that are 5.12 and lower, but is not guaranteed to work on 5.13. **v4.20.2

• Grey Dawn** supports most kernels that pre-date 5.0. If I specify v5.12.1 as the the compile fails under 5.14.0 as follows:

When you clone the repository and do a git branch you're on the main branch. As 5.14 is not released yet, there is not branch for it. So you have to use main. The branch you are on when you freshly clone the repo. If you type git branch it shows you which repo you are on.

@4nanook closing this one as I assume it worked out?
