[CRIU] [PATCH 0/2] cg: Optimize the prepare_cgroup_dir_properties stack usage

[Pavel Emelyanov]

Garrison,

I've noticed, that the call in question overuses the stack, we can make
it shorter. Here's the set, that does so, I've checked it manually with
pr_debug()-s having no props tests at hands. This set depends on the
previous one from me titled "Fixes and cleanups to cgroup code and tests"
and containing the ctrl_dir_and_opt() in the 4th patch.

Could you Ack that it doesn't break the properties restoration?

Thanks,
Pavel
