The default reader spining threshold is current set to 4096. However, the right reader spinning threshold may vary from one system to another and among the different architectures. This patch adds a new kernel boot parameter to modify the threshold value. This enables better tailoring to the needs of different systems as well as for testing purposes.
It also means that those systems could very easily be incorrectly tailored. (and worse case scenario: reboot, is obviously a terrible way to get rid of any issues). I very much disagree with exposing this sort of core stuff, it should work well for everyone out of the box, not relying on users to properly configure this.
