Subject: [PATCH 0/1] fs/nilfs2: Fix potential underflow in call to crc32_le

Hi Andrew,

Please send the following patch to upstream (hopefully in this cycle).
It fixes a memory overrun issue due to incomplete sanity check of
on-disk super block size information, which can result in a kernel
panic, for instance, in the case where a non-nilfs volume is
accidentally mounted through nilfs2.

The patch is applicable to the mainline as well as -mm tree.

Thanks,
Ryusuke Konishi
