block: fix 'kmem_cache of name 'bio-108' already exists'
[ Upstream commit b654f7a51ffb386131de42aa98ed831f8c126546 ]
Device mapper bioset often has big bio_slab size, which can be more than
1000, then 8byte can't hold the slab name any more, cause the kmem_cache
allocation warning of 'kmem_cache of name 'bio-108' already exists'.
Fix the warning by extending bio_slab->name to 12 bytes, but fix output
of /proc/slabinfo
