[PATCH 0/2] nilfs2: robustness fixes from Jake Labelle

[Ryusuke Konishi <konishi.ryusuke@gmail.com>]

Hi Viacheslav,

Please add the following two commits from Jake Labelle to your queue
for the next cycle.

As this cycle is getting closer to its end, I am sending these ahead with
a minor fix applied.  If Jake responds with further comments or revised
proposals later, we can discuss them as needed.

These patches address two robustness issues:

- Patch 1/2 rejects special inodes during dsync recovery to prevent
  dereferencing uninitialized bmap function pointers.
- Patch 2/2 validates and snaps the directory position after llseek in
  nilfs_readdir() to prevent invalid or out-of-bounds page reads.

For full context and background details, please refer to the original
cover letter here:

Thanks,
Ryusuke Konishi
