Revert "tty: Add a new VT mode which is like VT_PROCESS but doesn't require a VT_RELDISP ioctl call"
This reverts commit eec9fe7d1ab4a0dfac4cb43047a7657fffd0002f.
Ari writes as the reason this should be reverted:
The problems with this patch include:
1. There's at least one subtlety I overlooked - switching
between X servers (i.e. from one X VT to another) still requires
the cooperation of both X servers. I was assuming that KMS
eliminated this.
2. It hasn't been tested at all (no X server patch exists which
uses the new mode).
As he was the original author of the patch, I'll revert it.
