Regarding the review from Sachiko.
The AI review pointed out two things. a pre-existing issue and a valid
issue regarding swap_sync_discard().
For the pre-existing issue, I believe it is out of scope to address it
together in this patchset.
However, the second point is a valid issue. For the case where
swap_sync_discard() discards a non-selected tier, succeeds, and then
retries swap allocation. I will fix this in the next version by
checking the memcg mask within swap_sync_discard().
