Joe Lawrence cdee6bd650 kpatch: wait for module ref counts on unload ... There exists a very small timing window in which "kpatch unload" gets to its "rmmod" step before the kpatch-patch module's reference count has cleared and the "rmmod" fails. This is only a transient problem, but we can adopt code from upstream livepatch kselftests which wait for the module refcounts to settle before moving onto "rmmod". A small wrinkle is that this is not supported by the older kpatch.ko core. The price for circumventing the activeness safety check via KPATCH_FORCE_UNSAFE is that it must leave the kpatch patch modules in place (see e1890e627a ("prevent rmmod of forced modules")).
