Subjecthow to turn off, or to clear read cache?
Hi,

I need to make some performance tests. I need to switch off or to clear
read cache, so that consequent reading of the same file will take the
same amount of time.

Is there an easy way to do it, without rebuilding the kernel?

Please, put me on CC since I'm not subscriber of linux-kernel
