| Subject: hugetlbfs: fix inaccurate comment in hugetlbfs_statfs() |
| Date: Tue, 26 Jul 2022 22:29:18 +0800 |
| |
| In some cases, e.g. when size option is not specified, f_blocks, f_bavail |
| and f_bfree will be set to -1 instead of 0. Likewise, when nr_inodes |
| isn't specified, f_files and f_ffree will be set to -1 too. Update the |
| comment to make this clear. |
