mainline inclusion from mainline-5.0-rc1 commit 4e361e020e7220fa8fc812acdca4d08814633f49 category: backport
We have struct cached_dev allocated by kzalloc in register_bcache(), which initializes all the fields of cached_dev with 0s. And commit ce4c3e19e520 ("bcache: Replace bch_read_string_list() by __sysfs_match_string()") has remove the string "default".
Update the comment.
