From bb4067e34159648d394943d5e2a011f838bff22f Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 21 Dec 2006 21:20:01 +0100 Subject: [PATCH] [PATCH] elevator: fixup typo in merge logic The recent io scheduler allow_merge commit left the block layer with no merging, oops. This patch fixes that up. That means the CFQ change needs to be verified again, it might not fix the original bug now. But that's a seperate thing, I'll double check that tomorrow.
