Subject: f2fs: much larger batched trim_fs job
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=47b898081605684aa1bacd1d14443a50c660c1fe;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

f2fs: much larger batched trim_fs job

We have a kernel thread to issue discard commands, so we can increase the
number of batched discard sections. By default, now it becomes 4GB range.
