Subject: [PATCH 1/2] m1721: correct write caching

zeelog's write caching is not good for m1721 (even mido), it will get OOM when
coping large files.

After this commit, we will use min about 256 MiB and max about 512 MiB as write
caching. Also, writeback delays reduced to 60~300s (due to data loss).
