Subject: [PATCH v2 17/17] btrfs: unexport btrfs_get_io_geometry()
Date: Mon,  6 Dec 2021 10:29:37 +0800	[thread overview]
Message-ID: <20211206022937.26465-18-wqu@suse.com> (raw)
In-Reply-To: <20211206022937.26465-1-wqu@suse.com>

This function provides a lighter weight version of btrfs_map_block(),
just to provide enough info without filling everything of
btrfs_map_block().

But that function is only used for stripe boundary calculation, and now
stripe boundary calculation is all handled inside btrfs_map_bio(), there
is no need to export it anymore.
