Subject: ext4: use ktime_get_real_seconds for i_dtime
X-Git-Tag: v4.19-rc1~176^2~18

ext4: use ktime_get_real_seconds for i_dtime

We only care about the low 32-bit for i_dtime as explained in commit
b5f515735bea ("ext4: avoid Y2038 overflow in recently_deleted()"), so
the use of get_seconds() is correct here, but that function is getting
removed in the process of the y2038 fixes, so let's use the modern
ktime_get_real_seconds() here.
