For both sprout and seed fsids, btrfs_fs_devices::num_devices provides device count including missing btrfs_fs_devices::open_devices provides device count excluding missing We create a dummy struct btrfs_device for the missing device, so num_devices != open_devices when there is a missing device. In btrfs_rm_devices() we wrongly check for %cur_devices->open_devices before freeing the seed fs_devices. Instead we should check for %cur_devices->num_devices.

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.
