v3: - s/disgard/discard/, s/exit/return/ [DavidE] v2: - add r-bs for Dave - move mig_cmd_args reference later than index bound check [Dave] - use chars in tracepoints instead of number of steps [Dave] - add one patch for postcopy-run tracing
Some queued patches for ram disgard cleanup, and some debug probes. QEMU's ram disgard logic is probably a bit hard to predict because we send a bunch of packets to notify the disgarded ranges rather than sending the bitmap. The packets to send depending on the bitmap layout. Initially I thought it could be a problem but in reality it's fine so far per my initial measurement. So I'm flushing the cleanup/trace patches out because I think they're still helpful. Please have a look, thanks.
