[PATCH v2 OLK-6.6 0/2] kabi: restrict the KABI fix to a specific architecture and dist
by Xie XiuQi 13 Dec '24

13 Dec '24

Some distributions need to maintain and fix KABI compatibility so that drivers do not need to be recompiled during kernel upgrades. Fixing KABI compatibility is a dangerous and hacking job. Developers need to know clearly what they are doing and the risks they may face. KABI fix actions are closely related to the processor architecture. Fixes may not be appropriate for all architectures. Improper fix may cause kernel panic or unexpected error. Only for expert users, and select N by default.
