Subject: [PATCH 4.19 22/71] btrfs: Move btrfs_check_chunk_valid() to tree-check.[ch] and export it
Date: Mon, 9 Nov 2020 13:55:16 +0100 [thread overview]
Message-ID: <20201109125020.947045578@linuxfoundation.org> (raw)
In-Reply-To: <20201109125019.906191744@linuxfoundation.org>
From: Qu Wenruo <wqu@suse.com>
commit 82fc28fbedbb59642f05215db3b0ef4eb91aa31d upstream.
By function, chunk item verification is more suitable to be done inside
tree-checker.
So move btrfs_check_chunk_valid() to tree-checker.c and export it.
And since it's now moved to tree-checker, also add a better comment for
what this function is doing.
