[Qemu-devel] [PULL 06/17] dump: hoist lzo_init() from get_len_buf_out() to dump_init() |

dump_init()
lzo_init() <---------+
create_kdump_vmcore() |
write_dump_pages() |
get_len_buf_out() |
lzo_init() ------+
This patch doesn't change the fact that lzo_init() is called for every
LZO-compressed dump, but it makes get_len_buf_out() more focused (single
responsibility).
