Recently the extent update path started emmiting 0 size whiteouts on extent overwrite, as part of transitioning to moving extent handling out of the core btree code. Unfortunately, this broke the old code path that handles overlapping extents when reading in btree nodes - it relies on sorting incomming extents by start position, but the 0 size whiteouts broke that ordering. Skipping over them before the main algorithm sees them fixes this. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> 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 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.
