Commit2b45cef586("remoteproc: Further extend the vdev life cycle") extends kref support for vdev management. It introduces a regression when following sequence is executed: rproc_boot --> rproc_shutdown --> rproc_boot Second rproc_boot call crashes on register_virtio_device as device is already existing. Issue is previous vdev is never released when rproc is stop because associated refcount is too high. kref_get introduces is not needed as kref_init already initializes krefcount to 1 because it considers associated variable as used. This introduces a misalignment between kref_get and kref_put calls.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
