Subject: [PATCH 30/50] bcachefs: use the refcount instead of I_WILL_FREE|I_FREEING
Date: Thu, 21 Aug 2025 16:18:41 -0400 [thread overview]
Message-ID: <008961b8237f87429bcc1f8573d764dab2b1a22d.1755806649.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1755806649.git.josef@toxicpanda.com>
We can use the refcount to decide if the inode is alive instead of these
flags.
