From: Cong Wang <redacted>

This patchset introduces a new bpf hash map which has timeout.
Patch 1 is a preparation, patch 2 is the implementation of timeout
map, patch 3 contains a test case for timeout map. Please check each
patch description for more details.

This patch set seems to be breaking existing selftests. Please take a
look ([0]).
Also patch #3 should have a commit message, even if pretty trivial one.
