Commit2831231d4c("bcache: reduce cache_set devices iteration by devices_max_used") adds c->devices_max_used to reduce iteration of c->uuids elements, this value is updated in bcache_device_attach(). But for flash only volume, when calling flash_devs_run(), the function bcache_device_attach() is not called yet and c->devices_max_used is not updated. The unexpected result is, the flash only volume won't be run by flash_devs_run(). This patch fixes the issue by iterate all c->uuids elements in flash_devs_run(). c->devices_max_used will be updated properly when bcache_device_attach() gets called.

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.
