btw doesn't CONFIG_BLOCK_CACHE offer similar service, but for everyone and on block level ? I recall looking for ext4 fs speed up , but then ultimately used CONFIG_BLOCK_CACHE which did it for me.

I was unaware of the existence of CONFIG_BLOCK_CACHE - yes, that will solve the same problem by caching at the block level instead of the filesystem level. So my patch is redundant, and ext4 users should just be advised to turn on CONFIG_BLOCK_CACHE.
