Subject: [PATCH] f2fs: set highest IO priority for checkpoint thread
Date: Mon, 3 Mar 2025 22:17:30 +0000 [thread overview]
Message-ID: <20250303221730.1284822-1-jaegeuk@kernel.org> (raw)
The checkpoint is the top priority thread which can stop all the filesystem
operations. Let's make it RT priority.
