Currently, I patch my kernels to remove the automatic online TRIMs.
Is there a knob somewhere for this in the later kernels?

There is not automatic discard in any recent kernel.  You always need
to mount with -o discard to enabled it.

Peachy.  Thanks, Christoph.

My 2-year old userspace here doesn't have "-o discard",
so I couldn't find it in the man pages etc.. thus my paranoia.  :)

Cheers
