Josef Bacik d52be818e6 Btrfs: simplify unlink reservations ... Dave pointed out a problem where if you filled up a file system as much as possible you couldn't remove any files. The whole unlink reservation thing is convoluted because it tries to guess if it's going to add space to unlink something or not, and has all these odd uncommented cases where it simply does not try. So to fix this I've added a way to conditionally steal from the global reserve if we can't make our normal reservation. If we have more than half the space in the global reserve free we will go ahead and steal from the global reserve. With this patch Dave's reproducer now works and I can rm all the files on the file system.
