Subject: [PATCH 03/46] btrfs: Make btrfs_lookup_ordered_extent take btrfs_inode
Date: Mon,  1 Jun 2020 18:37:01 +0300	[thread overview]
Message-ID: <20200601153744.31891-4-nborisov@suse.com> (raw)
In-Reply-To: <20200601153744.31891-1-nborisov@suse.com>

It doesn't use the generic vfs inode for anything use btrfs_inode directly.
