When quota is disabled, we should not print 'journaled quota not supported'
when user tried to mount non-journaled quota. Also fix typo in the message.

Call dquot_drop() from ext3_dquot_drop() even if we fail to start a
transaction. Otherwise we never get to dropping references to quota
structures from the inode and umount will hang indefinitely. Thanks to
Payphone LIOU for spotting the problem.

* Add path_put() functions for releasing a reference to the dentry and
vfsmount of a struct path in the right order
* Switch from path_release(nd) to path_put(&nd->path)

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.
Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
<dentry,vfsmount> pairs
- it prepares the VFS for stacking support since it is essential to have a
struct path in every place where the stack can be traversed
- it reduces the overall code size:

with patch series:

This patch:
Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

Stop the EXT3 filesystem from using iget() and read_inode(). Replace
ext3_read_inode() with ext3_iget(), and call that instead of iget().
ext3_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.
ext3_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.

As it turns out, the kernel divides by EXT3_INODES_PER_GROUP(s) when
mounting an ext3 filesystem. If that number is zero, a crash follows.
Below a patch.
This crash was reported by Joeri de Ruiter, Carst Tankink and Pim Vullers.

This patch set supports large block size(>4k, <=64k) in ext3 just enlarging
the block size limit. But it is NOT possible to have 64kB blocksize on
ext3 without some changes to the directory handling code. The reason is
that an empty 64kB directory block would have a rec_len == (__u16)2^16 ==
0, and this would cause an error to be hit in the filesystem. The proposed
solution is treat 64k rec_len with a an impossible value like rec_len =
0xffff to handle this.
The Patch-set consists of the following 2 patches.
[1/2] ext3: enlarge blocksize
- Allow blocksize up to pagesize
[2/2] ext3: fix rec_len overflow
- prevent rec_len from overflow with 64KB blocksize
Now on 64k page ppc64 box runs with this patch set we could create a 64k
block size ext3, and able to handle empty directory block.

Slab constructors currently have a flags parameter that is never used. And
the order of the arguments is opposite to other slab functions. The object
pointer is placed before the kmem_cache pointer.
Convert
ctor(void *object, struct kmem_cache *s, unsigned long flags)
to
ctor(struct kmem_cache *s, void *object)
throughout the kernel

ext[234]_check_descriptors sanity checks block group descriptor geometry at
mount time, testing whether the block bitmap, inode bitmap, and inode table
reside wholly within the blockgroup. However, the inode table test is off
by one so that if the last block in the inode table resides on the last
block of the block group, the test incorrectly fails. This is because it
tests the last block as (start + length) rather than (start + length - 1).
This can be seen by trying to mount a filesystem made such as:
mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024
which yields:
EXT2-fs error (device loop0): ext2_check_descriptors: Inode table for group 0 not in group (block 101)!
EXT2-fs: group descriptors corrupted!
There is a similar bug in e2fsprogs, patch already sent for that.
(I wonder if inside(), outside(), and/or in_range() should someday be
used in this and other tests throughout the ext filesystems...)

Slab destructors were no longer supported after Christoph's
c59def9f22 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,
or the documentation references).
