I unpacked the RHEL5 kernel src.rpm.
The only patch applied to the vanilla 2.6.18 kernel for the isofs/ dir is
the elimination of any reference to the "inode->i_blksize" struct member,
but this is something they did across the board for all the file systems (it
was an official patch applied to the kernel.org kernel a few days after
2.6.18) and has nothing to do with actual isofs issues.

I made the same test (multi-extent 4.3 GB file) on kernel 2.4.33 and it
passed OK on that too.

So far I only tested loop-mounted isofs image files, not real DVD/BD-RE
media.

I'll do more test next week.

If someone has a procedure to get the multi-extent Linux problem to manifest
itself, please post it.

Thanks
