  - f2fs: avoid reading already updated pages during GC We found the following issue during fuzz testing:

    https://syzkaller.appspot.com/bug?extid=3686758660f980b402dc This case is consistent with the description     in commit 9bf1a3f (f2fs: avoid GC causing encrypted file corrupted): Page 1 is moved from blkaddr A to     blkaddr B by move_data_block, and after being written it is marked as uptodate. Then, Page 1 is moved from     blkaddr B to blkaddr C, VM_BUG_ON_FOLIO was triggered in the endio initiated by ra_data_block. There is no     need to read Page 1 again from blkaddr B, since it has already been updated. Therefore, avoid initiating     I/O in this case. (CVE-2026-53018)
