Hi Linus,
Please pull LED fixes for 4.20-rc2.
All three fixes are related to the newly added pattern trigger:
- remove mutex_lock() from timer callback, which would trigger problems
related to sleeping in atomic context, the removal is harmless since
mutex protection turned out to be redunda

Cgroup v1 implements the freezer controller, which provides an ability
to stop the workload in a cgroup and temporarily free up some
resources (cpu, io, network bandwidth and, potentially, memory)
for some other tasks. Cgroup v2 lacks this functionality.

Freezer.c will contain an implementation of cgroup v2 freezer,

The purpose of this patchset is to add a new class of locks called
terminal locks and converts some of the low level raw or regular

Add the x86 unoptimized static call implementation. For each key, it
creates a permanent trampoline which is the destination for all static
calls for the given key. The trampoline has a direct jump which gets
patched by static_call_update() when the destination changes.

Add the optimized static call implementation for x86-64. For each key,
a temporary trampoline is created, named __static_call_tramp_. The
trampoline has an indirect jump to the destination function.
Objtool uses the trampoline naming convention to detect all the call
sites. It then annotates th

Add a static call infrastructure. Static calls use code patching to
hard-code function pointers into direct branch instructions. They give
the flexibility of function pointers, but with improved performance.
This is especially important for cases where retpolines would otherwise
be used, as retpo

The maximum value for DEBUG_KMEMLEAK_EARLY_LOG_SIZE is only 4, so it
disables kmemleak every time on this aarch64 server running the latest mainline
(b00d209).
# echo scan > /sys/kernel/debug/kmemleak
-bash: echo: write error: Device or resource busy
Any idea on how to enable kmemleak there?

lockdep is much more powerful enforcing the locking rules than code comments,
so let's switch to it.
