[ Upstream commit b4993e64f78a9605b45252fa9ba385c88a1f4ce9 ] In case of deleting the seed device the %cur_devices (seed) and the %fs_devices (parent) are different. Now, as the parent fs_devices::total_devices also maintains the total number of devices including the seed device, so decrement its in-memory value for the successful seed delete. We are already updating its corresponding on-disk btrfs_super_block::number_devices value.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
