block: free both rq_map and request
Allocation:
__blk_mq_alloc_rq_map
blk_mq_alloc_rq_map
blk_mq_alloc_rq_map
tags = blk_mq_init_tags : kzalloc_node:
tags->rqs = kcalloc_node
tags->static_rqs = kcalloc_node
blk_mq_alloc_rqs
p = alloc_pages_node
tags->static_rqs[i] = p + offset;
Free:
blk_mq_free_rq_map
kfree(tags->rqs);
kfree(tags->static_rqs);
blk_mq_free_tags
kfree(tags);
The page allocated in blk_mq_alloc_rqs cannot be released,
so we should use blk_mq_free_map_and_requests here.
blk_mq_free_map_and_requests
blk_mq_free_rqs
__free_pages : cleanup for blk_mq_alloc_rqs
blk_mq_free_rq_map : cleanup for blk_mq_alloc_rq_map
