| H A D | main.c | df44f9f4 Fri Aug 06 11:26:48 CDT 2010 David Howells <dhowells@redhat.com> AFS: Fix the module init error handling
Fix the module init error handling. There are a bunch of goto labels for
aborting the init procedure at different points and just undoing what needs
undoing - they aren't all in the right places, however.
This can lead to an oops like the following:
