I did not realize that this was just the problem of coding in the ocfs module. Because this is not enabled in the kernel upstream, they (upstream developers) would not be interested in fixing the code. This has happened with the NTFS module -- it is broken in the 5.3 kernel and they officially declared no patches for that (although a dev provided a possible fix personally). So, you probably do not have much choice. Either try fixing the issue yourself or just disable it for now.

[CentOS] Building a kernel without kabichk

Currently, I¹m just trying to get the beast to build. I have been successful getting this to work on older versions like 2.6.18-92.1.22, but I have not had success with 128.1.6. l. I have not worried about build errors at this point, because I¹m hoping someone can say, ³Just do this, and all will be well.² I am relatively new to CentOS / RedHat, but I do have a significant amount of Linux experience building kernels.
