-+
-+ * configure.ac: Check for Linux device-mapper support.
-+
-+ * util/hostdisk.c (device_is_mapped): New function.
-+ (find_partition_start): New function, partly broken out from
-+ linux_find_partition and grub_util_biosdisk_get_grub_dev but with
-+ device-mapper support added.
-+ (linux_find_partition): Use find_partition_start.
-+ (convert_system_partition_to_system_disk): Add `st' argument.
-+ Support Linux /dev/mapper/* devices if device-mapper support is
-+ available; only DM-RAID devices are understood at present.
-+ (find_system_device): Add `st' argument. Pass it to
-+ convert_system_partition_to_system_disk.
-+ (grub_util_biosdisk_get_grub_dev): Pass stat result to
-+ find_system_device and convert_system_partition_to_system_disk. Use
-+ find_partition_start.
-+
-+ * conf/common.rmk (grub_mkdevicemap_SOURCES): Add kern/env.c,
-+ kern/err.c, kern/list.c, and kern/misc.c.
-+ * util/deviceiter.c [__linux__]: Define MINOR.
-+ (grub_util_iterate_devices): Add support for DM-RAID disk devices.
-+ * util/mkdevicemap.c (grub_putchar): New function.
-+ (grub_getkey): New function.
-+ (grub_refresh): New function.
-+ (main): Set debug=all if -v -v is used.
