Eric Biggers 0a12c4a806 fs/minix: fix block limit check for V1 filesystems 
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 6ed6a722f9 ("minixfs: fix block limit check")
fixed this in the V2 mapping code.  Fix it in the V1 mapping code too.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
