produced this warning:
WARNING: init/mounts.o(.text+0x192): Section mismatch in reference from the function devt_from_partuuid() to the variable .init.data:root_wait
The function devt_from_partuuid() references
the variable __initdata root_wait.
This is often because devt_from_partuuid lacks a __initdata
annotation or the annotation of root_wait is wrong.
Commit
185237e4cfab ("This patch makes two changes:"
init-add-root=partuuid=uuid-partnroff=%d-support-update.patch) adds the
reference to root_wait from the non-init function devt_from_partuuid().
The easiest thing to do is to remove __init_date from root_wait.
I have applied this patch as a merge fixup for today:
