I don't think there were any CFQ changes between feb 28 and march 5, so you could probably still try it out. A quicker way: - Edit .config and set CONFIG_DEBUG_INFO=y (near the bottom) - make oldconfig - rm block/cfq-iosched.o - make block/cfq-iosched.o - gdb block/cfq-iosched.o (gdb) l *cfq_dispatch_insert+0x28 and see what that says. Should not take you more than a minute or so, would appreciate it! -- Jens Axboe
