| H A D | recovery.c | diff 275b66b0 Mon Aug 29 09:58:34 MDT 2016 Chao Yu <chao@kernel.org> f2fs: support async discard Like most filesystems, f2fs will issue discard command synchronously, so when user trigger fstrim through ioctl, multiple discard commands will be issued serially with sync mode, which makes poor performance. In this patch we try to support async discard, so that all discard commands can be issued and be waited for endio in batch to improve performance.
