* btrfs-progs: volume: Fix a bug causing btrfs-find-root to skip first chunkQu Wenruo2016-02-26
| | | | | | | | | | | | | | | There is a small bug from 2011, where btrfs_next_bg (formally btrfs_next_metadata) function will always skip the first chunk. That's OK for that time, as there is always 3 empty temporary chunks. But now, we may ended up with only one metadata or system chunk, with empty chunk auto-remove from kernel or new mkfs.btrfs. So fix it by checking the initial value so btrfs_next_bg() will return the first chunk if its *logical parameter is 0.
