Linux kernel source tree

Rework the read path so that BCH_READ_NODECODE reads now also self-heal after a read error and a successful retry - prerequisite for scrub. - __bch2_read_endio() now handles a read that's both BCH_READ_NODECODE and a bounce. Normally, we don't want a BCH_READ_NODECODE read to ever allocate a split bch_read_bio: we want to maintain the relationship between the bch_read_bio and the data_update it's embedded in. But correcting read errors requires allocating a split/bounce rbio that's embedded in a promote_op. We do still have a 1-1 relationship, i.e. we only allocate a single split/bounce if it's a BCH_READ_NODECODE, so things hopefully don't get too crazy. - __bch2_read_extent() now is allowed to allocate the promote_op for rewriting after a failed read, even if it's BCH_READ_NODECODE.

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.
