Any chance they would make it a config option?
It is a config option, the
available settings are 100, 250, and 1000.
The problem is that the default has changed to 250.
Update: Linus has said that
this is a done deal. So now we need to
figure out how to work around it. I guess we'll have to go back to
using the RTC like on 2.4.
