After unclean shutdown, btree writes may have completed on one device and not others - and this inconsistency could lead us to writing new bsets with a gap in our btree node in one of our replicas. Fortunately, this is only an issue with bsets that are newer than the most recent journal flush, and we already have a mechanism for detecting and blacklisting those. We just need to make sure to start new btree writes after the most recent _non_ blacklisted bset. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
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 Restructured Text 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.
