Hi there,

My apologies if this is the wrong place to post this, but I was wondering if anyone had any information on whether or not the following patch has or will make its way into the CentOS Kernel?

https://patchwork.kernel.org/patch/10283095/

We are currently experiencing this problem with the latest version of CloudLinux (based on CentOS), so I believe it isn’t currently included. Is there any particular procedure to request a patch for future Kernel releases?

  • We have no idea what patches will go into the default CentOS kernels .. we rebuild the source code that Red Hat releases for RHEL.

    We do maintain several kernels on our own ..

    1. CentOS Plus kernel .. We add patches there, but it would need to be backported if it does not apply. We use this bug to maintain the Plus Kernel:

    2. Kernel in the AltArch tree .. We have to use a different kernel for armhfp, and we also build it for other CentOS arches .. it lives at:

    http://mirror.CentOS.org/altarch/7/kernel/

    This kernel is based on a kernel.org LTS kernel (currently 4.14.x) and if that patch gets rolled into the LTS stream, it will be in our kernels there.

    3. Experimential kernel in the AltArch tree .. this is a newer LTS
    kernel (which we will use in future armhfp releases .. it is currently based on 4.19.x LTS kernel.org kernel. This one will replace the 4.14
    kernel in the 7.7.x release whenever that happens. If that patch makes it into 4.19.x LTS at kernel.org then it will be in this kernel too.

    Thanks, Johnny Hughes

  • Just checked the current CentOS kernel and confirm that the patch is in there.

    [fs] xfs: detect agfl count corruption and reset agfl (Brian Foster) [1569471]

    It was added as of kernel 3.10.0-912.el7. In other words all 7.6.1810
    kernels are patched. What is the version of your running kernel?
