Subject: [PATCH 2.6.26] isofs: fix minor filesystem corruption
Some iso9660 images contain files with rockridge data that is either
incorrect or
incompletely parsed. Prior to commit
f2966632a134e865db3c819346a1dc7d96e05309,
(included with kernel 2.6.13) the kernel ignored the rockridge data for
these files,
while still allowing the files to be accessed under their non-rockridge
names. That commit
inadvertently changed things so that files with invalid rockridge data
could not be accessed
at all. (I ran across the problem when comparing some old CDs with hard
disk copies I had
made long ago under kernel 2.4: a few of the files on the hard disk
copies were no longer
visible on the CDs.)
This change reverts to the pre-2.6.13 behavior.
