Not something I can guess from the oops, sadly. Gcc has inlined
everything into logfs_mount, and the "0x44f/0x5cc" offset isn't very
helpful (with the same compiler version and config options it would be
possible to figure it out).

But looking at it, logfs_init_mapping() is currently called before
"s_freeing_list" is initialized, and it sets up at least
s_mapping_inode. So if anything fails between that point and the point
where we initialize s_freeing_list, I think we're toast.

I didn't check the other inodes, but at least that one does seem to be
potentially non-NULL. No?
