From: Manuel SchÃlling
Date: Wed Nov 16 2016 - 15:31:29 EST

Well, that's embarrassing: I changed the order of some local commits
in the last minute, so my patches included a compiler error.

Changes in v4.1:
- Fix compiler error
Changes in v4:
- Split into two patches
- Rework documentation
- Remove cosmetic changes in comments (postponed)
Changes in v3:
- Add config option for this feature
- Fallback to old scrollback buffer if kcalloc() fails
- Remove ioctl() call again and add documentation about existing
escape sequence to flush the scrollback buffer
Changes in v2:
- Add ioctl() call to flush scrollback buffer
- (Patch v2 was not labeled as such, sorry)

Manuel SchÃlling (2):
console: Move scrollback data into its own struct
console: Add persistent scrollback buffers for all VGA consoles
