Currently although the bcache code has a framework for multiple caches in a cache set, but indeed the multiple caches never completed and users use md raid1 for multiple copies of the cached data. This patch does the following change in struct cache_set, to explicitly make a cache_set only have single cache, - Change pointer array "*cache[MAX_CACHES_PER_SET]" to a single pointer "*cache". - Remove pointer array "*cache_by_alloc[MAX_CACHES_PER_SET]". - Remove "caches_loaded". Now the code looks as exactly what it does in practic: only one cache is used in the cache set. Signed-off-by: Coly Li <colyli@suse.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
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.
