Subject: [PATCH 02/18] bcachefs: s/BCH_LRU_FRAGMENTATION_START/BCH_LRU_BUCKET_FRAGMENTATION/
Date: Thu, 13 Feb 2025 13:45:47 -0500	[thread overview]
Message-ID: <20250213184607.18237-3-kent.overstreet@linux.dev> (raw)
In-Reply-To: <20250213184607.18237-1-kent.overstreet@linux.dev>

FRAGMENTATION_START was incorrect, there's currently only one
fragmentation LRU (at the end of the reserved bits for LRU type), and
we're getting ready to add a stripe fragmentation lru - so give it a
better name.
