reorganize few code blocks in super.c which
were needlessly indented (and hard to read):
so change from:
rettype fun()
{
init;
if (sth) {
long block of code;
}
}
to:
rettype fun()
{
init;
if (!sth)
return;
long block of code;
}
or
from:
rettype fun2()
{
init;
while (sth) {
init2();
if (sth2) {
long block of code;
}
}
}
to:
rettype fun2()
{
init;
while (sth) {
init2();
if (!sth2)
continue;
long block of code;
}
}

* kernel_timestamp type was almost unused - only callers of udf_stamp_to_time
and udf_time_to_stamp used it, so let these functions handle endianness
internally and don't clutter code with conversions
* rename udf_stamp_to_time to udf_disk_stamp_to_time
and udf_time_to_stamp to udf_time_to_disk_stamp

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /

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.

This patch does additional coding style fixup. Initially the code is being
distorted by Lindent (in my patches sent not very long ago) and fixed in
the followup patches but this stuff was accidently missed.
New and old compiled files were compared with cmp to check for being
identically. So the patch will not break the kernel.

This patch fix weird behaviour of UDF mounting procedure. To get UID
changed (for now) we have to type
mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point
and specifying two uid at once is strange a bit. So with the patch we are
able to mount without additional 'uid=ignore' option. The same for GID
option is done.
This patch will not break current mount scheme (with two option).
Btw this does fix (I hope) the following

Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.
This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,

I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by
SLAB.
I think its purpose was to have a callback after an object has been freed
to verify that the state is the constructor state again? The callback is
performed before each freeing of an object.
I would think that it is much easier to check the object state manually
before the free. That also places the check near the code object
manipulation of the object.
Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was
compiled with SLAB debugging on. If there would be code in a constructor
handling SLAB_DEBUG_INITIAL then it would have to be conditional on
SLAB_DEBUG otherwise it would just be dead code. But there is no such code
in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real
use of, difficult to understand and there are easier ways to accomplish the
same effect (i.e. add debug code before kfree).
There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be
clear in fs inode caches. Remove the pointless checks (they would even be
pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.
This is the last slab flag that SLUB did not support. Remove the check for
unimplemented flags from SLUB.

There's a bug where a UDF_PART_FLAG_READ_ONLY udf partition gets mounted
read-write, then subsequent problems happen; files seem to be able to be
removed, but file creation results in EIO or worse, oops.
EIO is coming from udf_new_block(), which returns EIO if the right flags
aren't set; only UDF_PART_FLAG_READ_ONLY is set in this case. We probably
s hould not have gotten this far...
Attached patch seems to fix it - and includes a printk to alert the user
that their "rw" mount request has been converted to "ro."
Here's the testcase I used:
[root@magnesium ~]# mkisofs -R -J -udf -o testiso /tmp/
...
Total translation table size: 0
Total rockridge attributes bytes: 342923
Total directory bytes: 382312

[root@magnesium ~]# mount -o loop testiso /mnt/test/

The following patch to udf_alloc_inode() should take care of both (and
other similar) cases, but I've only tested it with udf_lookup().

Give the statfs superblock operation a dentry pointer rather than a superblock
pointer.
This complements the get_sb() patch. That reduced the significance of
sb->s_root, allowing NFS to place a fake root there. However, NFS does
require a dentry to use as a target for the statfs operation. This permits
the root in the vfsmount to be used instead.
linux/mount.h has been added where necessary to make allyesconfig build
successfully.
Interest has also been expressed for use with the FUSE and XFS filesystems.
