Subject: net/sched: Add module aliases for cls_,sch_,act_ modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

No functional change intended, aliases will be used in followup commits.
Note for backporters: you may need to add aliases also for modules that
are already removed in mainline kernel but still in your version.

Patches were generated with the help of Coccinelle scripts like:

cat >scripts/coccinelle/misc/tcf_alias.cocci <<EOD
virtual patch
virtual report

@ haskernel @
@@

@ tcf_has_kind depends on report && haskernel @
identifier ops;
constant K;
@@

  static struct tcf_proto_ops ops = {
    .kind = K,
    ...
  };
+char module_alias = K;
EOD

/usr/bin/spatch -D report --cocci-file scripts/coccinelle/misc/tcf_alias.cocci \
        --dir . \
        -I ./arch/x86/include -I ./arch/x86/include/generated -I ./include \
        -I ./arch/x86/include/uapi -I ./arch/x86/include/generated/uapi \
        -I ./include/uapi -I ./include/generated/uapi \
        --include ./include/linux/compiler-version.h --include ./include/linux/kconfig.h \
        --jobs 8 --chunksize 1 2>/dev/null | \
        sed 's/char module_alias = "\([^"]*\)";/MODULE_ALIAS_NET_CLS("\1");/'

And analogously for:

  static struct tc_action_ops ops = {
    .kind = K,

  static struct Qdisc_ops ops = {
    .id = K,

(Someone familiar would be able to fit those into one .cocci file
without sed post processing.)
