zs_create_pool() currently takes a gfp flags argument that is used when growing the memory pool. However it is not used in allocating the metadata for the pool itself. That is currently hardcoded to GFP_KERNEL. zswap calls zs_create_pool() at swapon time which is done in atomic context, resulting in a "might sleep" warning. This patch changes the meaning of the flags argument in zs_create_pool() to mean the flags for the metadata allocation, and adds a flags argument to zs_malloc that will be used for memory pool growth if required.
