There are\ntwo types of controls - number of completed RCU updates invoked in a batch\n(blimit) and monitoring for high rate of incoming RCUs on a cpu (qhimark,\nqlowmark).\n\nBy default, the per-cpu batch limit is set to a small value.  If the input\nRCU rate exceeds the high watermark, we do two things - force quiescent\nstate on all cpus and set the batch limit of the CPU to INTMAX.  Setting\nbatch limit to INTMAX forces all finished RCUs to be processed in one shot.\n If we have more than INTMAX RCUs queued up, then we have bigger problems\nanyway.

Moving them to GPL -- but in a\nmeasured manner, as I proposed on this list some months ago -- is fine.\nChanging these particular exports precipitously is most definitely -not-\nfine.  Here is my earlier proposal:\n\n\thttp://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d110520930301813\u0026w\u003d2\n\nSee below for a patch that puts the exports back, along with an updated\nversion of my earlier patch that starts the process of moving them to GPL.\nI will also be following this message with RFC patches that introduce two\n(EXPORT_SYMBOL_GPL) interfaces to replace synchronize_kernel(), which then\nbecomes deprecated.\n\nSigned-off-by: \u003cpaulmck@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
