From 3045b3cb0b068c9f7601786841cda1e0b4647bd9 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Sat, 13 Dec 2008 17:44:59 +0000 Subject: [PATCH] powerpc: Remove dead BIO_VMERGE_BOUNDARY definition The block layer dropped the virtual merge feature (b8b3e16cfe6435d961f6aaebcfd52a1ff2a988c5). BIO_VMERGE_BOUNDARY definition is meaningless now (For POWER, BIO_VMERGE_BOUNDARY has been meaningless for a long time since POWER disables the virtual merge feature).
