Introduce new section reference annotations tags: __ref, __refdata, __refconst
Today we have the following annotations for functions/data
referencing __init/__exit functions / data:
__init_refok => for init functions
__initdata_refok => for init data
__exit_refok => for exit functions
There is really no difference between the __init and __exit
versions and simplify it and to introduce a shorter annotation
the following new annotations are introduced:
__ref => for functions (code) that
references __*init / __*exit
__refdata => for variables
__refconst => for const variables
Whit this annotation is it more obvious what the annotation
is for and there is no longer the arbitary division
between __init and __exit code.
The mechanishm is the same as before - a special section
is created which is made part of the usual sections
in the linker script.
We will start to see annotations like this:
-static struct pci_serial_quirk pci_serial_quirks[] = {
+static const struct pci_serial_quirk pci_serial_quirks[] __refconst = {
-----------------
-static struct notifier_block __cpuinitdata cpuid_class_cpu_notifier =
+static struct notifier_block cpuid_class_cpu_notifier __refdata =
----------------
-static int threshold_cpu_callback(struct notifier_block *nfb,
+static int __ref threshold_cpu_callback(struct notifier_block *nfb,
[The above is just random samples].
Note: No modifications were needed in modpost
to support the new sections due to the newly introduced
blacklisting.
