The following three sysfs files are created to display according feature set information of bcache: /sys/fs/bcache/<cache set UUID>/internal/feature_compat /sys/fs/bcache/<cache set UUID>/internal/feature_ro_compat /sys/fs/bcache/<cache set UUID>/internal/feature_incompat is added by this patch, to display feature sets information of the cache set. Now only an incompat feature 'large_bucket' added in bcache, the sysfs file content is: [large_bucket] string large_bucket means the running bcache drive supports incompat feature 'large_bucket', the wrapping [] means the 'large_bucket' feature is currently enabled on this cache set. This patch is ready to display compat and ro_compat features, in future once bcache code implements such feature sets, the according feature strings will be displayed in their sysfs files too.
