Subject: f2fs: fix to check warm_data_age_threshold
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9b13a8662ea61430005d3de3fc1d73e383b1ce5a;p=linux.git

f2fs: fix to check warm_data_age_threshold

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.
