uprobe helper functions to allocate probes

This macro is declared in upipe/uprobe_helper_alloc.h source file, line 67.

This macro declares two functions to allocate probes.

Supposing the name of your structure is uprobe_foo, it declares:

• struct uprobe_foo_alloc;

  A structure containing the probe and a urefcount.

• struct uprobe *uprobe_foo_alloc(...)

  A wrapper to uprobe_foo_init() which allocates the structure before.

• static void uprobe_foo_free(struct urefcount *urefcount)

  Called when the refcount goes down to zero, to deallocate the structure.

Please note that you must declare uprobe_foo_init and uprobe_foo_clean before this helper, and the macros ARGS_DECL and ARGS must be filled respectively with the declaration of arguments of uprobe_foo_alloc, and the use of them in the call to uprobe_foo_init.

Parameter list:

• STRUCTURE: name of your public uprobe super-structure your private uprobe structure
