Alex Henrie b02e6ba559 isofs: handle CDs with bad root inode but good Joliet root directory ... [ Upstream commit 4243bf80c7 ] I have a CD copy of the original Tom Clancy's Ghost Recon game from 2001. The disc mounts without error on Windows, but on Linux mounting fails with the message "isofs_fill_super: get root inode failed". The error originates in isofs_read_inode, which returns -EIO because de_len is 0. The superblock on this disc appears to be intentionally corrupt as a form of copy protection. When the root inode is unusable, instead of giving up immediately, try to continue with the Joliet file table. This fixes the Ghost Recon CD and probably other copy-protected CDs too.
