* bcache: fix a spurious gcc complaint, use scnprintfKent Overstreet2013-06-261-21/+22
| | | | | | | | | | An old version of gcc was complaining about using a const int as the size of a stack allocated array. Which should be fine - but using ARRAY_SIZE() is better, anyways. Also, refactor the code to use scnprintf(). Signed-off-by: Kent Overstreet <koverstreet@google.com>

* bcache: A block layer cacheKent Overstreet2013-03-231-0/+817
Does writethrough and writeback caching, handles unclean shutdown, and has a bunch of other nifty features motivated by real world usage. See the wiki at http://bcache.evilpiepirate.org for more. Signed-off-by: Kent Overstreet <koverstreet@google.com>
