| Subject: ocfs2: fix super block reserved field offset comment |
| Date: Thu, 7 Aug 2025 23:57:49 +0800 |
| |
| The offset annotation for s_reserved2 in struct ocfs2_super_block |
| was incorrect. After the preceding fields: |
| - s_xattr_inline_size (2 bytes at 0xB8) |
| - s_reserved0 (2 bytes at 0xBA) |
| - s_dx_seed[3] (12 bytes at 0xBC) |
| |
| The actual offset of s_reserved2 is at 0xC8, when calculating from the |
| start of the structure. |
| |
| Correct the offset comment from C0 to C8 to reflect the proper location in |
| the super block structure. |
