writeback: allow the file system to override MIN_WRITEBACK_PAGES
The relatively low minimal writeback size of 4MiB means that written back
inodes on rotational media are switched a lot. Besides introducing
additional seeks, this also can lead to extreme file fragmentation on
zoned devices when a lot of files are cached relative to the available
writeback bandwidth.
Add a superblock field that allows the file system to override the
default size.
