----------------------------------------
The patch "bcache: remove PTR_CACHE" introduces a compiling failure in debug.c with following error message, In file included from drivers/md/bcache/bcache.h:182:0, from drivers/md/bcache/debug.c:9: drivers/md/bcache/debug.c: In function 'bch_btree_verify': drivers/md/bcache/debug.c:53:19: error: 'c' undeclared (first use in this function) bio_set_dev(bio, c->cache->bdev); ^ This patch fixes the regression by replacing c->cache->bdev by b->c-> cache->bdev.
