From: Matthew Wilcox Date: Mon, 4 Dec 2006 10:38:31 +0000 (-0700) Subject: [PATCH] Centralise definitions of sector_t and blkcnt_t X-Git-Tag: v2.6.20-rc2~6^2~13^2~7 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e62438630ca37539c8cc1553710bbfaa3cf960a7;p=linux-2.6-omap-h63xx.git [PATCH] Centralise definitions of sector_t and blkcnt_t 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.
