Make sure inodes can be allocated in new space added by xfs_growfs.
Regression test for
xfs: allow inode allocations in post-growfs disk space
Signed-off-by: Eryu Guan <eguan@xxxxxxxxxx>
---
v2:
- test on 16M xfs to make test quicker, ~70s -> ~10s
- use _require_fs_space to check $SCRATCH_MNT space
- reduce inode consumer count to agcount * 2, not hardcoded 1000
- expect 99% inode usage, not absolute number 0 of free inode
- new _get_total_inode and _get_used_inode helper, and keep
_get_free_inode helper which could benefit other tests
