      lib/iov_iter: initialize "flags" in new pipe_buffer · 9d2231c5
      Max Kellermann authored 
      The functions copy_page_to_iter_pipe() and push_pipe() can both
allocate a new pipe_buffer, but the "flags" member initializer is
missing.

      Without the terminator, if a con_id is passed to gpio_find() that
does not exist in the lookup table the function will not stop looping
correctly, and eventually cause an oops.

      tools/cgroup/slabinfo: update to work with struct slab · 22194473
      Roman Gushchin authored 
      After the introduction of the dedicated struct slab to describe slab
pages by commit d122019b ("mm: Split slab into its own type") and
the following removal of the corresponding struct page's fields by
commit 07f910f9 ("mm: Remove slab from struct page") the
memcg_slabinfo tool broke. An attempt to run it produces a trace like
this:
Traceback (most recent call last):
  File "/usr/bin/drgn", line 33, in <module>
    sys.exit(load_entry_point('drgn==0.0.16', 'console_scripts', 'drgn')())

    main()
  File "memcg_slabinfo.py", line 199, in main
    cache = page.slab_cache
AttributeError: 'struct page' has no member 'slab_cache'

The problem can be fixed by explicitly casting struct page * to struct
slab * for slab pages. The tools works as expected with this fix, e.g.:

      slab: remove __alloc_size attribute from __kmalloc_track_caller · 93dd04ab
      Greg Kroah-Hartman authored 
      Commit c37495d6 ("slab: add __alloc_size attributes for better
bounds checking") added __alloc_size attributes to a bunch of kmalloc
function prototypes.  Unfortunately the change to __kmalloc_track_caller
seems to cause clang to generate broken code and the first time this is
called when booting, the box will crash.

While the compiler problems are being reworked and attempted to be
solved [1], let's just drop the attribute to solve the issue now.  Once
it is resolved it can be added back.

      Input: psmouse - set up dependency between PS/2 and SMBus companions · 7b1f781f
      Dmitry Torokhov authored 
      When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
create SMBus companion devices that are attached to I2C/SMBus controllers.
However, when suspending and resuming, we also need to make sure that we
take into account the PS/2 device they are associated with, so that PS/2
device is suspended after the companion and resumed before it, otherwise
companions will not work properly. Before I2C devices were marked for
asynchronous suspend/resume, this ordering happened naturally, but now we
need to enforce it by establishing device links, with PS/2 devices being
suppliers and SMBus companions being consumers.

Fixes: 172d9319 ("i2c: enable async suspend/resume on i2c client devices")
