From e6c474723dc66cd4765fd09453d6b48bd5905ba4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Sun, 20 Apr 2014 13:57:26 -0400 Subject: [PATCH] udev: warn when name_to_handle_at is not implemented We have a bunch of reports from people who have a custom kernel and are confused why udev is not running. Issue a warning on error. Barring an error in the code, the only error that is possible is ENOSYS. https://bugzilla.redhat.com/show_bug.cgi?id=1072966 --- src/libudev/libudev-monitor.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/libudev/libudev-monitor.c b/src/libudev/libudev-monitor.c index c05cb3e511b..186e5e1e873 100644 --- a/src/libudev/libudev-monitor.c +++ b/src/libudev/libudev-monitor.c @@ -119,8 +119,11 @@ static bool udev_has_devtmpfs(struct udev *udev) { int r; r = name_to_handle_at(AT_FDCWD, "/dev", &h.handle, &mount_id, 0); - if (r < 0) + if (r < 0) { + if (errno != EOPNOTSUPP) + udev_err(udev, "name_to_handle_at on /dev: %m\n"); return false; + } f = fopen("/proc/self/mountinfo", "re"); if (!f)
