[Ocfs2-tools-devel] debufs.ocfs2: issue cat command against some of the system files cause core dump

[jeff.liu]

Hello,

issue command 'cat' against some of the OCFS2 system files in
debugfs.ocfs2 cause core dump.
for example:
-----------
debugfs.ocfs: cat //global_bitmap
debugfs.ocfs2: extend_file.c:211: ocfs2_new_path: Assertion
`root_el->l_tree_depth < 5' failed.
Aborted (core dumped)

looks the command get some unexpected data just cause the assertion
failed. :(

I am wonder whether the system files could be cat or not, the patch
checking if the target to cat is a system file, if yes, just return and
show user
the related message.


Thanks,
Jeff
