When converting bits for an extent range (btrfs_convert_extent_bit()), if the current extent state record starts after the target range, we always do a jump to the 'search_again' label, which will cause us to do a full tree search for the next state if the current state ends before the target range. Unless we need to reschedule, we can just grab the next state and process it, avoiding a full tree search, even if that next state is not contiguous, as we'll allocate and insert a new prealloc state if needed.

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.
