fs/minix: fix block limit check for V1 filesystems
[ Upstream commit 0a12c4a8069607247cb8edc3b035a664e636fd9a ]
The minix filesystem reads its maximum file size from its on-disk
superblock. This value isn't necessarily a multiple of the block size.
When it's not, the V1 block mapping code doesn't allow mapping the last
possible block. Commit 6ed6a722f9ab ("minixfs: fix block limit check")
fixed this in the V2 mapping code. Fix it in the V1 mapping code too.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
