When below kernel config items are set, compiling error are triggered.

------------------------------------------------------
CONFIG_KEXEC is used to enable kexec_load interface, the
crash_notes/crash_notes_size/crash_hotplug showing depends on
CONFIG_KEXEC is incorrect. It should depend on KEXEC_CORE instead.
Fix it now.

In fact it's the patch 1 which exposes the wrong ifdeffery. I can shift the order in v2. Thanks. > > > Signed-off-by: Baoquan He <bhe@redhat.com> >

Can we add Fixes/CC stable, so it gets eventually backported into 6.6?

Makes sense. Will add it in v2 since I need respin to add the missing
stuff in patch 1. Thanks.

Please avoid mixing cc:stable patches and this-merge-window fixes in the same series as next-merge-window material. Because I'll just have to separate them out anyway, causing what-I-merged to unnecessarily differ from what-you-sent.

Got it, will send them separately because the issue that this patch is fixing has been there for very long time. Thanks for noticing.
