Aborted tests
-------------
Tests that didn't complete running successfully are marked with β‘β‘β‘.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with π§. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with β±.
Depending on CONFIG_VMAP_STACK and the THREAD_SIZE / PAGE_SIZE ratio
the space for task stacks can be allocated using __vmalloc_node_range(),
alloc_pages_node() and kmem_cache_alloc_node(). In the first and the
second cases page->mem_cgroup pointer is set, but in the third it's
not: memcg membership of a slab page should be determined using the
memcg_from_slab_page() function, which looks at
page->slab_cache->memcg_params.memcg . In this case, using
mod_memcg_page_state() (as in account_kernel_stack()) is incorrect:
page->mem_cgroup pointer is NULL even for pages charged to a non-root
memory cgroup.
It can lead to kernel_stack per-memcg counters permanently showing 0
on some architectures (depending on the configuration).
In order to fix it, let's introduce a mod_memcg_obj_state() helper,
which takes a pointer to a kernel object as a first argument, uses
mem_cgroup_from_obj() to get a RCU-protected memcg pointer and
calls mod_memcg_state(). It allows to handle all possible
configurations (CONFIG_VMAP_STACK and various THREAD_SIZE/PAGE_SIZE
values) without spilling any memcg/kmem specifics into fork.c .
Note: this patch has been first posted as a part of the new slab
controller patchset. This is a slightly updated version: the fixes
tag has been added and the commit log was extended by the advice
of Johannes Weiner. Because it's a fix that makes sense by itself,
I'm re-posting it as a standalone patch.
Fixes: 4d96ba353075 ("mm: memcg/slab: stop setting page->mem_cgroup pointer for slab pages")
