Not true, and this patch will break the BGRT code. bgrt_init, which does indeed have an __init annotation, stores bgrt_image and bgrt_image_size into the .private and .size fields of a sysfs bin_attribute, which does *not* have an __initdata annotation, and which will get read whenever the user reads the corresponding sysfs attribute. > Signed-off-by: Jan Beulich <jbeul...@suse.com> > Cc: <m...@redhat.com> > Link: http://lkml.kernel.org/r/50afb29f02000078000aa...@nat28.tlf.novell.com > Signed-off-by: Ingo Molnar <mi...@kernel.org> > --- > arch/x86/platform/efi/efi-bgrt.c | 7 ++++--- > 1 file changed, 4 insertions(+), 3 deletions(-) > > diff --git a/arch/x86/platform/efi/efi-bgrt.c > b/arch/x86/platform/efi/efi-bgrt.c > index d9c1b95..7145ec6 100644 > --- a/arch/x86/platform/efi/efi-bgrt.c > +++ b/arch/x86/platform/efi/efi-bgrt.c > @@ -11,20 +11,21 @@ > * published by the Free Software Foundation. > */ > #include <linux/kernel.h> > +#include <linux/init.h> > #include <linux/acpi.h> > #include <linux/efi.h> > #include <linux/efi-bgrt.h> > > struct acpi_table_bgrt *bgrt_tab; > -void *bgrt_image; > -size_t bgrt_image_size; > +void *__initdata bgrt_image; > +size_t __initdata bgrt_image_size; > > struct bmp_header { > u16 id; > u32 size; > } __packed; > > -void efi_bgrt_init(void) > +void __init efi_bgrt_init(void) > { > acpi_status status; > void __iomem *image; > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
