From: duguowei <duguowei@xiaomi.com>
If there are more than one f2fs sbi, there will be more discard threads. But the comm is too long to show dev minor. So, change the default prefix of thread from "f2fs_discard" to "f2fs_dcd".
Before: $ ps -e | grep f2fs 1628 ? 00:00:00 f2fs_ckpt-7:10 1629 ? 00:00:00 f2fs_flush-7:10 1630 ? 00:00:00 f2fs_discard-7: 1631 ? 00:00:00 f2fs_gc-7:10 2030 ? 00:00:00 f2fs_ckpt-7:27 2031 ? 00:00:00 f2fs_flush-7:27 2032 ? 00:00:00 f2fs_discard-7: 2033 ? 00:00:00 f2fs_gc-7:27
After: $ ps -e | grep f2fs 1628 ? 00:00:00 f2fs_ckpt-7:10 1629 ? 00:00:00 f2fs_flush-7:10 1630 ? 00:00:00 f2fs_dcd-7:10 1631 ? 00:00:00 f2fs_gc-7:10 2030 ? 00:00:00 f2fs_ckpt-7:27 2031 ? 00:00:00 f2fs_flush-7:27 2032 ? 00:00:00 f2fs_dcd-7:27 2033 ? 00:00:00 f2fs_gc-7:27
