Even if the RAID stripe-tree is not enabled in the filesystem, do_free_extent_accounting() still calls into btrfs_delete_raid_extent(). Check if the extent in question is on a block-group that has a profile which is used by RAID stripe-tree before attempting to delete a stripe extent. Return early if it doesn't, otherwise we're doing a unnecessary search.

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.
