| H A D | recovery.c | diff 275b66b09e85cf0520dc610dd89706952751a473 Mon Aug 29 10:58:34 CDT 2016 Chao Yu <yuchao0@huawei.com> 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.
