Is someone more informed on the workings of the Linux kernel (specifically redhats flavour) able to point me in the direction of some more detail about this:
Due to the nature of changes required, a kpatch for customers running Red Hat Enterprise Linux 7.2 or greater will NOT be available
Just wondering what changed between 7.1 -> 7.2 that made this something that couldn't be updated live and there doesn't seem to be a ton of obvious extra information about the nuances of this change around.
- gtirloni 9y agokpatch was a Technology Preview in 7.1 and only became officially supported in 7.2 https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/7.2_release_notes/kernel https://access.redhat.com/documentation/en-us/red_hat_enterp...

Ah, I completely missed that it was a technology preview in 7.1 Presumably what that snippet is actually saying is "there will be no way to avoid a reboot due to the nature of this change" rather than "rhel 7.2+ will require a reboot but 7.0 and 7.1 won't" Thanks for the clarification.
- hoffie 9y agoI think this is related to kpatch only being available as of RHEL 7.2 [1] in general. In other words, this must not necessarily be caused by any specifics of the current kernel patches.
