Add a function for scrubbing btree nodes - reading them in, and kicking off a rewrite if there's an error. The btree_node_read_done() checks have to be duplicated because we're not using a pointer to a struct btree - the btree node might already be in cache, and we need to check a specific replica, which might not be the one we previously read from. This will be used in the next patch implementing high-level scrub. 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.
