Impact: Section mismatch
The function kmemleak_alloc() is called from kernel allocators. kmemleak_alloc() calls log_early() but being log_early() marked as __init it causes following section mismatches. Being called from kernel allocators, kmemleak_allock() will be called after freeing up the init memory and log_early() will also called. So, unmarking __init from log_early() fixes the warning. If anything else please notice.
LD mm/built-in.o WARNING: mm/built-in.o(.text+0x4f371): Section mismatch in reference from the function kmemleak_alloc() to the function .init.text:log_early() The function kmemleak_alloc() references the function __init log_early(). This is often because kmemleak_alloc lacks a __init annotation or the annotation of log_early is wrong.
WARNING: mm/built-in.o(.text+0x4f470): Section mismatch in reference from the function kmemleak_free() to the function .init.text:log_early() The function kmemleak_free() references the function __init log_early(). This is often because kmemleak_free lacks a __init annotation or the annotation of log_early is wrong.
WARNING: mm/built-in.o(.text+0x4f56f): Section mismatch in reference from the function kmemleak_not_leak() to the function .init.text:log_early() The function kmemleak_not_leak() references the function __init log_early(). This is often because kmemleak_not_leak lacks a __init annotation or the annotation of log_early is wrong.
WARNING: mm/built-in.o(.text+0x4f66e): Section mismatch in reference from the function kmemleak_ignore() to the function .init.text:log_early() The function kmemleak_ignore() references the function __init log_early(). This is often because kmemleak_ignore lacks a __init annotation or the annotation of log_early is wrong.
WARNING: mm/built-in.o(.text+0x4f786): Section mismatch in reference from the function kmemleak_scan_area() to the function .init.text:log_early() The function kmemleak_scan_area() references the function __init log_early(). This is often because kmemleak_scan_area lacks a __init annotation or the annotation of log_early is wrong.
WARNING: mm/built-in.o(.text+0x4f885): Section mismatch in reference from the function kmemleak_no_scan() to the function .init.text:log_early() The function kmemleak_no_scan() references the function __init log_early(). This is often because kmemleak_no_scan lacks a __init annotation or the annotation of log_early is wrong.
Thanks.
