Re: [PATCH v8 1/4] fs/proc/kcore: avoid bounce buffer for ktext data

Hi,


I met this too when I executed below command to trigger a kcore reading.
I wanted to do a simple testing during system running and got this.

   makedumpfile --mem-usage /proc/kcore

Later I tried your above objdump testing, it corrupted system too.


What do you mean with "corrupted system too" -- did it not only fail to dump the system, but also actually harmed the system?

@Lorenzo do you plan on reproduce + fix, or should we consider reverting that change?
