From 1d29b5b0499c4d1f0415fadf94e41ed8964a7ed3 Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Tue, 7 Feb 2017 21:27:22 +0800 Subject: [PATCH] virtio-blk: Remove useless condition around g_free() Laszlo spotted and studied this wasteful "if". He pointed out: The original virtio_blk_free_request needed an "if" as it accesses one field, since 671ec3f05655 ("virtio-blk: Convert VirtIOBlockReq.elem to pointer", 2014-06-11); later on in f897bf751fbd ("virtio-blk: embed VirtQueueElement in VirtIOBlockReq", 2014-07-09) the field became embedded, so the "if" became unnecessary (at which point we were using g_slice_free(), but it is the same. Now drop it.
