Subject: SquashFS io errors -  zlib_inflate tried to decompress too much
 data

Hi Phillip,

With 2.6.29-rc7-git5 (x86, 32bit) I get the following errors on assumed
correct squashfs images (generated with mksquashfs from CVS, dated
2009-03-14)

[ 3481.692558] SQUASHFS error: zlib_inflate tried to decompress too much data, expected 8192 bytes.  Zlib data probably corrupt
[ 3481.692571] SQUASHFS error: squashfs_read_data failed to read block 0x29375e0
[ 3481.692579] SQUASHFS error: Unable to read metadata cache entry [29375e0]
[ 3481.692586] SQUASHFS error: Unable to read inode 0x6a04a05ed

The same happens on 2.6.28.8 with all squashfs patches from 2.6.29-rc8
applied to it (x86, 64bit).

If useful I can provide the image (44MiB), it's an image of Gentoo
portage tree.

Bruno
