Hi, I am a developer who worked on CentOS. Recently I am working on porting one of my block drivers from CentOS 6.x to CentOS 7.x. In newest kernel (kernel-3.10.0-693.17.1.el7) I found there is an issue in submit_bio()'s first argument: void submit_bio(int rw, struct bio *bio) The type of bi_rw of struct bio is unsigned long, and the number of enum rq_flags_bits also exceeds 32, so we

I googled this issue and found so many people have encountered, but most of them just said "the newer kernel doesn't have this problem, so upgrade kernel". We can't upgrade kernel easily, so we need to *really* solve this problem.

Hi, Recently, I encountered a interesting phenomenon that CentOS 6.3 running as normal even if I (my colleague, actually) installed a kernel that build for CentOS 7.x (e.g. kernel-3.10.0-327.el7.x86_64.rpm). I found kernel is mismatch accidentally when I using "uname -r" to check kernel version. So my question is what the harmness we will get if I install a el7 rpm into a el6 system?

What do you mean? Wouldn't the kernel version always be the actual running version of the kernel that was booted?

I know dracut can update modules in initramfs, but I think it is too slow. So I'm wondering what is the fastest way to update modules in initramfs of CentOS 7? Thanks!

Hi I have a small question about NIC driver (e.g. i40e) loading. Who is responsible to load i40e driver? And how does he knows we should load i40e, instead of ixgbe? Thanks.

Hi, I have a specific needs that requires yum do not to uninstall old version when install new one. For example, I found that yum install kernel will install new kernel, and old kernel will remained. But yum install <something-else> will uninstall old version after install new one, how to disable it? Thanks.

Hi, I following the steps described in https://wiki.centos.org/Sources to get centos7.x kernel repo. But I'm wondering how to get centos6.x kernel repo. Because when checkout branch 'c6' and found that there is nothing. Thanks
