However creating an alias without +specifying the minor doesn't allow us to create the node ahead, +triggerring module auto-load when it's first accessed. + +Starting with depmod from kmod 16 we started to warn if there's a +devname alias without specifying the major and minor. + +Let's do the same done for uhid, kvm, fuse and others, specifying a +fixed minor. In systems with systemd as the init the following will +happen: on early boot systemd will call "kmod static-nodes" to read +/lib/modules/$(uname -r)/modules.devname and then create the nodes. When +first accessed these "dead" nodes will trigger the module loading. + +Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> +Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> +Signed-off-by: Marcel Holtmann <marcel@holtmann.org> +--- + Documentation/devices.txt | 1 + + drivers/bluetooth/hci_vhci.c | 3 ++- + include/linux/miscdevice.h | 1 + + 3 files changed, 4 insertions(+), 1 deletion(-) + +diff --git a/Documentation/devices.txt b/Documentation/devices.txt +index 80b7241..fce9398 100644 +--- a/Documentation/devices.txt ++++ b/Documentation/devices.txt +@@ -353,6 +353,7 @@ Your cooperation is appreciated. + 133 = /dev/exttrp External device trap + 134 = /dev/apm_bios Advanced Power Management BIOS + 135 = /dev/rtc Real Time Clock ++ 137 = /dev/vhci Bluetooth virtual HCI driver + 139 = /dev/openprom SPARC OpenBoot PROM + 140 = /dev/relay8 Berkshire Products Octal relay card + 141 = /dev/relay16 Berkshire Products ISO-16 relay card +diff --git a/drivers/bluetooth/hci_vhci.c b/drivers/bluetooth/hci_vhci.c +index 7b16738..59095e6 100644 +--- a/drivers/bluetooth/hci_vhci.c ++++ b/drivers/bluetooth/hci_vhci.c +@@ -352,7 +352,7 @@ static const struct file_operations vhci_fops = { + static struct miscdevice vhci_miscdev= { + .name = "vhci", + .fops = &vhci_fops, +- .minor = MISC_DYNAMIC_MINOR, ++ .minor = VHCI_MINOR, + }; + + static int __init vhci_init(void) +@@ -378,3 +378,4 @@ MODULE_DESCRIPTION("Bluetooth virtual HCI driver ver " VERSION); + MODULE_VERSION(VERSION); + MODULE_LICENSE("GPL"); + MODULE_ALIAS("devname:vhci"); ++MODULE_ALIAS_MISCDEV(VHCI_MINOR); +diff --git a/include/linux/miscdevice.h b/include/linux/miscdevice.h +index f7eaf2d..e5db611 100644 +--- a/include/linux/miscdevice.h ++++ b/include/linux/miscdevice.h +@@ -23,6 +23,7 @@ + #define TEMP_MINOR 131 /* Temperature Sensor */ + #define RTC_MINOR 135 + #define EFI_RTC_MINOR 136 /* EFI Time services */ ++#define VHCI_MINOR 137 + #define SUN_OPENPROM_MINOR 139 + #define DMAPI_MINOR 140 /* DMAPI */ + #define NVRAM_MINOR 144 +-- +1.9.0 + |
