>> WARNING: modpost: vmlinux.o(.text.unlikely+0x66b8): Section mismatch in reference from the function disk_unlock_native_capacity() to the variable .init.data:initcall_level_names
The function disk_unlock_native_capacity() references
the variable __initdata initcall_level_names.
This is often because disk_unlock_native_capacity lacks a __initdata
annotation or the annotation of initcall_level_names is wrong.
