# \[PATCH AUTOSEL 5.11 060/104\] virtiofs: fix userns - From: Sasha Levin \ - Date: 2021-05-05 16:46:25 - List: virtualization - Page: https://ratatoskr.run/virtualization/2021/05/205381 - Thread: https://ratatoskr.run/stable/2021/05/6358731/t.md ```text From: Miklos Szeredi [ Upstream commit 0a7419c68a45d2d066b996be5087aa2d07ce80eb ] get_user_ns() is done twice (once in virtio_fs_get_tree() and once in fuse_conn_init()), resulting in a reference leak. Also looks better to use fsc->user_ns (which *should* be the current_user_ns() at this point).
