From: "Tzvetomir Stoyanov (VMware)" <tstoyanov@xxxxxxxxxx> Currently the size of one buffer page is global for all buffers and it is hard coded to one system page. The patch set introduces configurable ring buffer page size, per ring buffer. A new user space interface is introduced, which allows to change the page size of the ftrace buffer, per ftrace instance.
