I'm already queuing up a bunch of (more) fixes... there's more weird things I
didn't notice.  Such as, why is current_fs now defined in current_inode.h?
That really ought to have stayed in debugfs.c, and current_inode.h should have
'extern ext2_filsys current_fs;', no?

Also there's a no-return-value 'return;' if the inline data write fails later
down in that function, and I think it's time to pull in cppcheck on a make
C=1 build.

...I'll also respin the patchset I sent out a few days ago.
