Heh, I wouldn't worry about keeping me busy.  Too busy really.

I have a patch attached.  I think it should be fine.  I haven't
released yet since I've been away, caught up working on other stuff
and hunting hunting a remaining bug.  This should be as solid on w/
BProc 3.2.5 as anything else though.  Apply the kernel patch as usual
and make this one little change in bproc/kernel/interface.c:

Change:
    inode = get_empty_inode();
to:
    inode = new_inode(bprocfs_mnt->mnt_sb);
