Yeah, but gcc thinks it is smarter than us...
Probably it drops the test, assuming UB cannot happen.
Hmm, sounds like a GGC bug to me then. Not sure how to fix

Yes, you are right.

But I think that the total data blocks allocated of filesystem between two

hot_data_age_threshold is a non-zero positive number, and
condition 2 includes condition 1, so there is no need to
additionally judge whether t is 0. And let's remove it.

Commit 71644dff4811 ("f2fs: add block_age-based extent cache")
introduce age extent cache, which experimental data is based on
a 128G storage device, and hot and warm data age threshold are
set to 1G and 10G respectively. But it is unreasonable to set
this value to 1G or 10G by default, which varie
hot_data_age_threshold is a non-zero positive number, and
condition 2 includes condition 1, so there is no need to
additionally judge whether t is 0. And we need to judge
whether hot_data_age_threshold exceeds the number of available
blocks.
