[PATCH] fix creating zero sized bio mempools in low memory system
In the very low memory systems is in the init_bio call scale parameter set to zero and it leads to creating zero sized mempool. This patch prevents pool_entries parameter become zero, so the created pool have at least 1 entry. Mempool with 0 entries lead to incorrect behaviour of mempool_free. (Alloc requests are not waken up and system stalls in mempool_alloc->ioschedule). Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
