Kernel option to disable TRIM/discard system-wide?

[Peter Rabbitson <rabbit+list@rabbit.us>]

Hello!

I have looked through the archives, but can not find anything even 
remotely related to the subject:

I want to disable trim on my system for good - yet there seems to be no 
kernel boot parameter for this.

My rationale is simple: I want best data integrity guarantees, followed 
by better battery-life + mechanical robustness (I throw my laptop around 
a lot), and only last am I concerned about performance.

There seem to be a new TRIM-related bug discovered every couple months 
for quite some time now. Combined with the "metadata leak via dm-crypt" 
makes it a no-brainer decision that I want to avoid TRIM system-wide.

I currently have my sytsem configured properly, but I am concerned a 
future OS upgrade will introduce some well meaning cron-job or something 
along these lines that will re-enable discards without me ever noticing.

Is there a boot parameter I can hard-code for forward-compatible peace 
of mind?

Thank you!
