If GFP_KERNEL are garanteeded to succeed that is a showstopper bug. We also have another showstopper bug in getblk that will be hard to fix because people was used to rely on it and they wrote dealdock prone code. You should know that people not running benchmarks and and using the machine power for simulations runs out of memory all the time. If you put this kind of obvious deadlock into the main kernel allocator you'll screwup the hard work to fix all the other deadlock problems during OOM that is been done so far. Please fix raid1 instead of making things worse. Andrea -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
