-   NOTE: In the case where the user removed a removable-media-disk even if
-   there's still dirty data not synced on disk (due a bug in the device driver
-   or due an error of the user), by not destroying the dirty buffers we could
-   generate corruption also on the next media inserted, thus a parameter is
-   necessary to handle this case in the most safe way possible (trying
-   to not corrupt also the new disk inserted with the data belonging to
-   the old now corrupted disk). Also for the ramdisk the natural thing
-   to do in order to release the ramdisk memory is to destroy dirty buffers.
-
-   These are two special cases. Normal usage imply the device driver
-   to issue a sync on the device (without waiting I/O completion) and
-   then an invalidate_buffers call that doesn't trash dirty buffers.
-
-   For handling cache coherency with the blkdev pagecache the 'update' case
-   is been introduced. It is needed to re-read from disk any pinned
-   buffer. NOTE: re-reading from disk is destructive so we can do it only
-   when we assume nobody is changing the buffercache under our I/O and when
-   we think the disk contains more recent information than the buffercache.
-   The update == 1 pass marks the buffers we need to update, the update == 2
-   pass does the actual I/O. */

-	  label, i.e. DOS partition table.  It does not support GPT labelled
-	  Dynamic Disks yet as can be created with Vista.
-
-	  Windows 2000 introduced the concept of Dynamic Disks to get around
-	  the limitations of the PC's partitioning scheme.  The Logical Disk
-	  Manager allows the user to repartition a disk and create spanned,
-	  mirrored, striped or RAID volumes, all without the need for
-	  rebooting.
-
-	  Normal partitions are now called Basic Disks under Windows 2000, XP,

- * TODO:
- *
- * Changelog:
- * Mon Nov 09 2004 Matt Domsch <Matt_Domsch@dell.com>
- * - test for valid PMBR and valid PGPT before ever reading
- *   AGPT, allow override with 'gpt' kernel command line option.
- * - check for first/last_usable_lba outside of size of disk
- *
- * Tue  Mar 26 2002 Matt Domsch <Matt_Domsch@dell.com>
- * - Ported to 2.5.7-pre1 and 2.5.7-dj2
- * - Applied patch to avoid fault in alternate header handling
- * - cleaned up find_valid_gpt
- * - On-disk structure and copy in memory is *always* LE now - 
- *   swab fields as needed
- * - remove print_gpt_header()
- * - only use first max_p partition entries, to keep the kernel minor number
- *   and partition numbers tied.
- *
- * Mon  Feb 04 2002 Matt Domsch <Matt_Domsch@dell.com>
- * - Removed __PRIPTR_PREFIX - not being used
- *
- * Mon  Jan 14 2002 Matt Domsch <Matt_Domsch@dell.com>
- * - Ported to 2.5.2-pre11 + library crc32 patch Linus applied
- *
- * Thu Dec 6 2001 Matt Domsch <Matt_Domsch@dell.com>
- * - Added compare_gpts().
- * - moved le_efi_guid_to_cpus() back into this file.  GPT is the only
- *   thing that keeps EFI GUIDs on disk.
- * - Changed gpt structure names and members to be simpler and more Linux-like.
- * 
- * Wed Oct 17 2001 Matt Domsch <Matt_Domsch@dell.com>
- * - Removed CONFIG_DEVFS_VOLUMES_UUID code entirely per Martin Wilck
- *
- * Wed Oct 10 2001 Matt Domsch <Matt_Domsch@dell.com>
- * - Changed function comments to DocBook style per Andreas Dilger suggestion.
- *
- * Mon Oct 08 2001 Matt Domsch <Matt_Domsch@dell.com>
- * - Change read_lba() to use the page cache per Al Viro's work.
- * - print u64s properly on all architectures
- * - fixed debug_printk(), now Dprintk()
- *
- * Mon Oct 01 2001 Matt Domsch <Matt_Domsch@dell.com>
- * - Style cleanups
- * - made most functions static
- * - Endianness addition
- * - remove test for second alternate header, as it's not per spec,
- *   and is unnecessary.  There's now a method to read/write the last
- *   sector of an odd-sized disk from user space.  No tools have ever
- *   been released which used this code, so it's effectively dead.
- * - Per Asit Mallick of Intel, added a test for a valid PMBR.
- * - Added kernel command line option 'gpt' to override valid PMBR test.
- *
- * Wed Jun  6 2001 Martin Wilck <Martin.Wilck@Fujitsu-Siemens.com>
- * - added devfs volume UUID support (/dev/volumes/uuids) for
- *   mounting file systems by the partition GUID. 
- *
- * Tue Dec  5 2000 Matt Domsch <Matt_Domsch@dell.com>
- * - Moved crc32() to linux/lib, added efi_crc32().
- *
- * Thu Nov 30 2000 Matt Domsch <Matt_Domsch@dell.com>
- * - Replaced Intel's CRC32 function with an equivalent
- *   non-license-restricted version.
- *
- * Wed Oct 25 2000 Matt Domsch <Matt_Domsch@dell.com>
- * - Fixed the last_lba() call to return the proper last block
- *
- * Thu Oct 12 2000 Matt Domsch <Matt_Domsch@dell.com>
- * - Thanks to Andries Brouwer for his debugging assistance.
- * - Code works, detects all the partitions.
