Problem:
1, using contiguous conter for type identify is not uniform distribution
when compress for some tasks;
2, zram driver will alloc per-cpu contex for zstd, which will cause
about 3MB memory;
Solution:

selection;
2, create 2 context: one dedicated for kswapd task; another one
dedicated for direct reclaim;
