ACPICA: Mark acpi_ut_create_internal_object_dbg() memory allocations as non-leaks

2018-05-27T10:23:03+00:00

In kernel 4.17.0-rcX, kmemleak reports 9 leaks with tracebacks similar to
the following:

unreferenced object 0xffff880224a077e0 (size 72):
  comm "swapper/0", pid 1, jiffies 4294892358 (age 1022.636s)

    [<0000000024681a1d>] kernel_init_freeable+0x1a2/0x237

According to gdb, the offending code is
              object =
                  acpi_ut_allocate_object_desc_dbg(module_name, line_number,
                                                   component_id);

As it is not possible to unload the ACPI code to test that this is a real
leak and not a false positive, and that only these 9 appear no matter how
long the system is up, a kmemleak_not_leak(object) call is inserted.

ACPICA: Implement deferred resolution of reference package elements

2017-08-03T21:34:17+00:00

ACPICA commit 0c08790c56fdf0dc081ae869495a09d8c4230854

This change defers the resolution of package elements that
are named references until after the entire namespace has been
loaded from the definition block. This allows such references
to be in fact forward references for both module level code
and control methods.
