Subject: [PATCH 44/50] ext4: remove reference to I_FREEING in orphan.c
Date: Thu, 21 Aug 2025 16:18:55 -0400	[thread overview]
Message-ID: <cd9f2a5d78d6863fa529da33950e5f2f0f26de60.1755806649.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1755806649.git.josef@toxicpanda.com>

We can use the i_count refcount to see if this inode is being freed.
