From 3bc217ffe6774e7971d6a7ce6350ce806ebab044 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 1 Feb 2008 11:34:49 +0100 Subject: block: kill swap_io_context() It blindly copies everything in the io_context, including the lock. That doesn't work so well for either lock ordering or lockdep. There seems zero point in swapping io contexts on a request to request merge, so the best point of action is to just remove it.
