A quick check for memcpy finds that __btrfs_close_devices() does a memcpy of btrfs_device structs w/o initializing the lock in the new copy, but I have no idea whether that's the place we are looking for.Cool, you found one, thanks! I'm setting boobytraps. Um, correction, box says I'm setting _buggy_ boobytraps :) Tomorrow-man will test this and frob traps anew.What kind of test setup do you have? i.e. raid, single disk ...
