Re: [PATCH] block: fix bio-cache for passthru IO

commit <8af870aa5b847> ("block: enable bio caching use for passthru IO") introduced bio-cache for passthru IO. In case when nr_vecs are greater than BIO_INLINE_VECS, bio and bvecs are allocated from mempool (instead of percpu cache) and REQ_ALLOC_CACHE is cleared. This causes the side effect of not freeing bio/bvecs into mempool on completion.

This patch lets the passthru IO fallback to allocation using bio_kmalloc when nr_vecs are greater than BIO_INLINE_VECS. The corresponding bio is freed during call to blk_mq_map_bio_put during completion.

Applied, thanks!
