fcbf7637e6 udf: Fix signed/unsigned format specifiers
Fix problems noted in compilion with -Wformat=2 -Wformat-signedness.
In particular, a mismatch between the signedness of a value and the
signedness of its format specifier can result in unsigned values being
printed as negative numbers, e.g.:

  Partition (0 type 1511) starts at physical 460, block length -1779968542

...which occurs when mounting a large (> 1 TiB) UDF partition.

Changes since V1:
* Fixed additional issues noted in udf_bitmap_free_blocks(),
  udf_get_fileident(), udf_show_options()

b490bdd630 udf: Fix 64-bit sign extension issues affecting blocks > 0x7FFFFFFF
Large (> 1 TiB) UDF filesystems appear subject to several problems when
mounted on 64-bit systems:

* readdir() can fail on a directory containing File Identifiers residing
  above 0x7FFFFFFF. This manifests as a 'ls' command failing with EIO.

* FIBMAP on a file block located above 0x7FFFFFFF can return a negative
  value. The low 32 bits are correct, but applications that don't mask the
  high 32 bits of the result can perform incorrectly.

Per suggestion by Jan Kara, introduce a udf_pblk_t type for representation
of UDF block addresses. Ultimately, all driver functions that manipulate
UDF block addresses should use this type; for now, deployment is limited
to functions with actual or potential sign extension issues.

Changes to udf_readdir() and udf_block_map() address the issues noted
above; other changes address potential similar issues uncovered during
audit of the driver code.

8076c363da udf: Rename udf_error to udf_err
Rename udf_error to udf_err for consistency with normal logging
uses of pr_err.

Rename function udf_err to _udf_err.
Remove __func__ from uses and move __func__ to a new udf_err
macro that calls _udf_err.
Some of the udf_error uses had \n terminations, some did not so
standardize \n's to udf_err uses, remove \n from _udf_err function.
Coalesce udf_err formats.
One message prefixed with udf_read_super is now prefixed with
udf_fill_super.

7e273e3b41 udf: Promote some debugging messages to udf_error
If there is a problem with a scratched disc or loader, it's valuable to know
which error occurred.

Convert some debug messages to udf_error, neaten those messages too.
Add the calculated tag checksum and the read checksum to error message.
Make udf_error a public function and move the logging prototypes together.

f4bcbbd92e udf: Fix handling of multisession media
According to OSTA UDF specification, only anchor blocks and primary volume
descriptors are placed on media relative to the last session. All other block
numbers are absolute (in the partition or the whole media). This seems to be
confirmed by multisession media created by other systems.

15aebd2866 udf: move headers out include/linux/
There's really no reason to keep udf headers in include/linux as they're
not used by anything but fs/udf/.

This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h,
include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and
include/linux/udf_fs.h into fs/udf/udfdecl.h.

The only thing remaining in include/linux/ is a stub of udf_fs_i.h
defining the four user-visible udf ioctls.  It's also moved from
unifdef-y to headers-y because it can be included unconditionally now.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
