Subject: [PATCH 3/6] bcachefs: Mark recovery passses that are safe to run online
Date: Wed, 6 Dec 2023 15:33:07 -0500 [thread overview]
Message-ID: <20231206203313.2197302-4-kent.overstreet@linux.dev> (raw)
In-Reply-To: <20231206203313.2197302-1-kent.overstreet@linux.dev>
Online fsck is coming, and many of our recovery/fsck passes are already
safe to run while the filesystem is in use - mark which ones.
