Subject: f2fs: do not issue small discard commands during checkpoint
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9ac00e7cef106b66611e131f59f61f5ae35cf726;p=linux.git

f2fs: do not issue small discard commands during checkpoint

If there're huge # of small discards, this will increase checkpoint latency
insanely. Let's issue small discards only by trim.
