Subject: [f2fs-dev] [PATCH] f2fs: modify task name prefix
Date: Mon, 18 Jul 2022 16:10:38 +0800 [thread overview]
Message-ID: <20220718081038.2279-1-duguoweisz@gmail.com> (raw)
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
