When the patch for "livepatch: add (un)patch callbacks" was posted to the mailing list at:
https://lkml.kernel.org/r/[email protected] ... it was based on top of the following commit: ef8daf8eeb5b ("livepatch: unpatch all klp_objects if klp_module_coming fails"). But when it was applied to git on the livepatching for-4.15/shadow-variables branch, that branch was missing the above commit. The patch was rebased accordingly: 93862e385ded ("livepatch: add (un)patch callbacks") Then the two above commits were merged into livepatching/for-next: 6a18fdf2d8d3 ("Merge branch 'for-4.15/callbacks' into for-next"), The result of the merge commit was that the klp_post_unpatch_callback() call in the klp_cleanup_module_patches_limited() function disappeared. The original patch on the mailing list had that call, so put it back.
