Data move -> move_get_io_opts -> bch2_get_update_rebalance_opts requires a not_extents iterator; this fixes the path where we're walking the extents btree and chase a reflink pointer into the reflink btree. bch2_lookup_indirect_extent() requires working with an extents iterator (due to peek_slot() semantics), so we implement bch2_lookup_indirect_extent_for_move(). This is simplified because there's no need to report indirect_extent_missing_errors here, that can be deferred until fsck or when a user reads that data.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
