Hey Eric, sorry to throw you under the bus, but...

1.316 (eparis 11-Aug-09): CONFIG_IMA=y

Perhaps we should stop merging crap into the kernel if it's not supposed
to be enabled. (Granted, IMA is better than 99% of the random junk
merged in a release, it actually has somewhat useful Kconfig help text,
unlike the thousands of crap drivers that get merged which provide no
hint to what obscure medieval ARM board found only on three silicon
revisions two of which were never released they were for.)

The Kconfig description sounds generally useful to me. If it's bloated
crap, how did it get merged?

Sigh.
