The second revision to SUSE's kGraft
mechanism for live kernel patching of running systems is now available.
SUSE developers continue to pursue mainlining their kGraft approach that's an alternative to the existing Kslice option or Red Hat's Kpatch
mechanism for live kernel patching. To date there's been no concerted effort to try to merge these kGraft and Kpatch solutions. Today's revision to kGraft addresses developer comments during the first round of upstream kernel developer review.
These 21 kGraft patches represent just under one thousand lines of new code on the kernel-side while this round of patches is still seeking additional developer review and comments.
Those interested in checking out kGraft can find the patches on the kernel mailing list
. For those interested, you can try out kGraft on Ubuntu Linux
for patching a running Linux kernel -- Canonical so far in this kernel patching fad seems to be siding with SUSE's technology.
