Subject: [PATCH 17/45] xfs: make the start pointer passed to btree alloc_block functions const
Date: Wed, 19 Jan 2022 16:18:56 -0800	[thread overview]
Message-ID: <164263793644.860211.12363495651254985480.stgit@magnolia> (raw)
In-Reply-To: <164263784199.860211.7509808171577819673.stgit@magnolia>

From: Darrick J. Wong <djwong@kernel.org>

Source kernel commit: deb06b9ab6dfa167c280a68d5acb2f12e007073f

The @start pointer passed to each per-AG btree type's ->alloc_block
function isn't supposed to be modified, since it's a hint about the
location of the btree block being split that is to be fed to the
allocator, so mark the parameter const.
