Linux uses it only if SHRINKER_DEBUG config option is enabled. Ignore it.

It takes the lock and release it immediately to make sure no shrinkers
are running in parallel.

bz@ asked if the KBI breakage is a concern here. My answer was that this
is the first time in the DRM drivers in Linux 5.13 (the version I'm
working on) that this structure is initialized (as a variable local to
the function in this case), so it shouldn't be a problem for the DRM
drivers.
However, I can't speak for other drivers maintained outside of the src
tree.

A driver can register a shrinker that will be called when the kernel
wants to free some memory.
Add support for that in linuxkpi and call the registered shrinkers
when the lowmem event is triggered.
