Parted 1.6.21

[Andrew Clausen]

Hi all,

Changes:
* libparted/disk.c, doc/parted.texi : renamed prep-boot prep partition
  name to prep.
* libparted/linux.c (linux_disk_commit): if the BLKPG method fails, try
  the BLKRRPART method.
* libparted/disk_dos.c (msdos_write): put in a unique identifier (which
  is misleadingly called the "MBR signature" by Microsoft docs and
  EFI specs).  Based on a patch by Matt Domsch <address@hidden>.
* include/parted/endian.h : fixed PED_SWAP macros missing (), since it
  broke on 64bit hardware as shown in the PED_CPU_TO_BE32(part ? part_num :
LINK_END)
  code snipplet, which applied the uint32 cast to part, and not the value.
* libparted/disk_amiga.c, libparted/fs_amiga/amiga.c : Added some uint32
  casts.
* libparted/disk_sun.c (sun_alloc, sun_read, sun_write): fixed
  cylinder recording stuff.  pcylcount is now 2 more, and ncyl is now
  2 less than it was before.
* libparted/filesys.c (ped_file_system_clobber): removed a useless
  (always-thrown) assertion for file system support for clobbering.
* libparted/gnu.c (gnu_new): Added three new variables ro_err, rw_err
  and ispath.  The ispath variables is set to 1 if path is indeed a path
  and not a store type name.  This prevents having to use strchr more then
  once.  Added a check for determining if the inputted path is a path and
  not a store-type name.  If (const char *)path is a path then use
  store_open (). If (const char *)path is a store-type name use
  store_typed_open ().
* libparted/linux.c (_disk_sync_part_table): removed duplicate error message.
* libparted/linux.c (_device_get_part_path): only treat the device as
  devfs if it has /disc on the end.
* libparted/linux.c (_partition_get_part_dev): added.
* libparted/linux.c (_partition_is_mounted_by_dev ): added.
* libparted/linux.c (_partition_is_mounted): now uses
  _partition_is_mounted_by_dev().  This is more reliable than guessing
  the partition's device name.
* libparted/linux.c (_device_probe_type): sets the type to
  PED_DEVICE_UNKNOWN on block devices that don't fall into the
  standard categories.  This makes libparted correctly update
  the kernel's view of partition tables, etc.
* libparted/disk_dos.c (probe_partition_for_geom): improved heuristic
  for finding broken partition tables: test if any feasible solution
  geometry exists against the end cylinder rather than 1024.  This
  heuristic now has fewer false negatives and no false positives.

Cheers,
Andrew
