When I try to run fallocate with "--keep-size" on my btrfs partitions, it's failing, and I'm at a loss as to why. This was working in prior versions.
Any suggestions on how to attack this problem? I'm betting I'm missing something simple here, and have just gone down the rabbit hole... BTW, I've confirmed that the line that fails is fallocate.c:368 [2], with "open" always returning -1.
