add_disk() takes an extra reference on disk->queue, which is put in put_disk() -> disk_release(). Avoiding blk_cleanup_queue() (which also puts the queue) until add_disk() sets GENHD_FL_UP works for the queue itself, but leaks various queue internals. Conditioning tag_set freeing on GENHD_FL_UP is wrong too: all error paths after rbd_init_disk() leak the tag_set. Move the final "announce" steps out of rbd_dev_device_setup() so that it can be unwound like any other function. Leave "announce" steps to do_rbd_add/remove().

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.
