[2/2] fixes a bug which appears to go all the way back to 5.10. The bugfix patch has a dependency on the cleanup, which is unfortunate. We could add the Fixes: to [1/1] and add cc:stable to both patches so they get backported into -stable kernels together. But I think it's nicer to just concentrate on the single bugfix patch (with Fixes: and cc:stable) and do the cleanup later, in the usual fashion. So can I suggest a resend please? _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
