[PATCH] Unify CONFIG_LBD and CONFIG_LSF handling
From: Matthew Wilcox
Date: Mon Jun 19 2006 - 18:15:02 EST
CONFIG_LBD and CONFIG_LSF are spread into asm/types.h for no particularly
good reason. Centralising the definition in linux/types.h means that arch
maintainers don't need to bother adding it, as well as fixing the problem
with x86-64 users being asked to make a decision that has absolutely no
effect. The H8/300 porters seem particularly confused since I'm not aware
of any microcontrollers that need to support 2TB filesystems these days.
