From 574f2cf39e37ac6ecdb6d9b8b38626b4d6502822 Mon Sep 17 00:00:00 2001
From: Ray Strode <rstrode@redhat.com>
Date: Mon, 25 Sep 2023 22:22:08 +0200
Subject: [PATCH 1/3] util: Add way to print backtraces
Now that mutter can use a realtime thread its very important that
it doesn't stall for too long, since that can result in the kernel
killing it. Ironically, a main reason mutter could stall is
kernel bugs.
When a stall happens, we need a way to see why. This commit adds
a new function, "meta_print_backtrace" to print backtrace of the
current process and the kernel (if possible).
A future commit will use this new function.

From 2c78762dfe3dc05febe6be6408e4018be048159e Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/3] clutter: Add ms2ns helper
Some system apis we're going to need in the future use
nanoseconds, but we're never going to need more timing
precision that milliseconds.
In preparate for that, this commit adds a new helper ns2ms
to help avoid bugs in unit conversion.
