after ten consecutive open failures. Scanning all the way up to
10000 is excessive and can cause serious performance problems in
some configurations.
Fixes Ubuntu bug #787461.
* grub-core/kern/emu/getroot.c (grub_find_device): Recognize
dir == /dev/mapper.
(grub_guess_root_device): Use already known os_dev if possible.
* grub-core/kern/emu/hostdisk.c
(convert_system_partition_to_system_disk): Scan only in /dev/mapper
if device is known to be a dm one.

* grub-core/kern/emu/getroot.c (grub_util_is_dmraid): Removed.
(grub_util_is_lvm): New function.
(grub_util_get_dev_abstraction): Assume dmraid if not lvm rather
than lvm if not dmraid.
Handle mapped md nodes.
* grub-core/kern/emu/hostdisk.c (device_is_mapped): Rename to ...

updated.
(grub_util_get_dm_node_linear_info) [HAVE_DEVICE_MAPPER]: New function.

New function.
(grub_util_biosdisk_close): Use grub_util_biosdisk_flush.
* include/grub/emu/hostdisk.h (grub_util_biosdisk_flush): New proto.
* util/grub-setup.c (setup): Use grub_util_biosdisk_flush.
Build fixes for GNU/kFreeBSD.
* Makefile.util.def: Add `$(LIBZFS) $(LIBNVPAIR)' library dependencies
to programs that require ZFS conversion.
* grub-core/kern/emu/hostdisk.c (grub_util_biosdisk_is_floppy): Support
kernels that don't have FLOPPY_MAJOR.
convert partition names to disk names if the new `convert' parameter
is set.
(grub_util_biosdisk_get_grub_dev): If opening the disk device
returns GRUB_ERR_UNKNOWN_DEVICE, treat the partition device as a
disk in its own right. This can happen with Xen disk images.

the verbosity of later #ifs.
(find_partition_start): Define this function on FreeBSD too.
(device_is_wholedisk) [__FreeBSD__ || __FreeBSD_kernel__]: New
function.
(grub_util_biosdisk_get_grub_dev): Use partition-start-sector logic
on FreeBSD.

* grub-core/kern/emu/hostdisk.c (read_device_map): Don't
canonicalise device paths under /dev/mapper/.
(convert_system_partition_to_system_disk): Compare the
uncanonicalised path to /dev/mapper/ rather than the canonicalised
path, since device nodes under /dev/mapper/ are often symlinks.

All users updated.
(options): Remove partitions. All users updated.
* util/grub-fstest.c (fstest): Don't pass "-p" to loopback.
