What is the reason for the config option?  The only thing that it
controls is setting of a single flag.

I wanted to be conservative and give users the option to disable this on
their kernel. Would you prefer if I drop it?

I don't think adding an option per file system scales in any way.  If
there is some strong urge to disable the functionality (which I see no
reason for) we could add something like a global sysctl for all on-disk
file systems.

Sounds reasonable. I'm dropping the config options.
