bch2_btree_increase_depth() was originally for disaster recovery, to get some data back from the journal when a btree root was bad. We don't need it for that purpose anymore; on bad btree root we'll launch btree node scan and reconstruct all the interior nodes. If there's a key in the journal for a depth that doesn't exists, and it's not from check_topology/btree node scan, we should just ignore it. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
