From 9cf16b380af5bab7d0952b9aad0601ebf986de69 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Fri, 22 Sep 2023 13:49:05 +0200 Subject: fsconfig: ensure that dirfd is set to aux The code in fs_param_is_fd() expects param->dirfd to be set to the fd that was used to set param->file to initialize result->uint_32. So make sure it's set so users like autofs using FSCONFIG_SET_FD with the new mount api can rely on this to be set to the correct value.
