File 0075-9pfs-fix-memory-leak-in-v9fs_link.patch of Package qemu.19028
From: Li Qiang <liqiang6-s@360.cn> Date: Mon, 17 Oct 2016 14:13:58 +0200 Subject: 9pfs: fix memory leak in v9fs_link The v9fs_link() function keeps a reference on the source fid object. This causes a memory leak since the reference never goes down to 0. This patch fixes the issue.
