Subject: [PATCH 2/8] btrfs: drop argument tree from submit_extent_page
Date: Wed,  5 Feb 2020 19:09:28 +0100	[thread overview]
Message-ID: <a54487df38bbbd4f6149b2a7bbe86247fe5c532e.1580925977.git.dsterba@suse.com> (raw)
In-Reply-To: <cover.1580925977.git.dsterba@suse.com>

Now that we're sure the tree from argument is same as the one we can get
from the page's inode io_tree, drop the redundant argument.
