So a kernel patch is uneeded? So why James Mastros had a filesystem panic
after running the offending script? And how can be useful a tree that can'
t be reached in any way?
At least for my own system I like my patch to be allowed to run the script
and delete the PAGE_SIZE long tree with rm -r. For my system 4096
character of path are well.
