Details

As a media cache, anonymous temporary file is used to a cache. In b2g, flash seems to be used for it. The flash could be a performance bottle neck. It might be better to have a choice to use RAM as a media cache on gonk if b2g phone has more RAM.

Need to care about not to consume all RAMs on the phone.

I wrote a patch for this a few years ago, as an experiment. I can no longer find the patch, but if I recall correctly, the easy way to do this is to implement a new FileBlockCache that writes to memory instead of writing to disk.
Is this a regression or not? What's the user impact if this is not fixed?

It is not necessary as 2.0. Clear "2.0?" flag. It could improve the http streaming performance, if a b2g device has a lot of RAM.
