Phillip Lougher a3f94cb99a Squashfs: Compute expected length from inode size rather than block length ... Previously in squashfs_readpage() when copying data into the page cache, it used the length of the datablock read from the filesystem (after decompression). However, if the filesystem has been corrupted this data block may be short, which will leave pages unfilled. The fix for this is to compute the expected number of bytes to copy from the inode size, and use this to detect if the block is short.
