fit to the FS - change the way we calculate free space and use
leb_overhead instead of dark_wm in calculations.

The TNC mutex is unlocked prematurely when reading leaf nodes
with non-hashed keys. This is unsafe because the node may be
moved by garbage collection and the eraseblock unmapped, although
that has never actually happened during stress testing.

Leaf-nodes that have a hashed key are stored in the

mutex. Consequently, when reading a leaf node with

the TNC mutex is always required.

Always allow truncations to zero, even if budgeting thinks there
is no space. UBIFS reserves some space for deletions anyway.
Otherwise, the following happans:

2. truncate the file, which fails with ENOSPC, which is not good.

Xattr code has not been tested for a while and there were

'ubifs_jnl_change_xattr()'. The other is a deadlock in
'ubifs_setxattr()': the i_mutex is locked in

At the moment UBIFS reserves twice old index size space for the

node are very fragmented and there are many small gaps, while the

Thus, reserve trise as more, in which case we are guaranteed that

Orphan inodes are deleted inodes which will disappear after FS

they are not needed on the flash media.
So optimize orphans a little by not writing them back. Just mark

UBI transparently handles write errors by automatically copying
and remapping the affected eraseblock. If UBI is unable to do
that, for example its pool of eraseblocks reserved for bad block
handling is empty, then the error is propagated to UBIFS. UBIFS
must protect the media from falling into an inconsistent state
by immediately switching to read-only mode. In the case of log

Although the inode is marked as clean when it is being deleted,
it might stay and be used as orphan, and be marked as dirty.
So we have to free the budget when we delete it.

The 'ubifs_release_dirty_inode_budget()' was buggy and incorrectly
freed the budget, which led to not freeing all dirty data budget.
This patch fixes that.
Also, this patch fixes ubifs_mkdir() which passed 1 in dirty_ino_d,
which makes no sense. Well, it is harmless though.
Also, add few more useful assertions. And improve few debugging
messages.

We encouredge people to mount using volume name, not device
numbers. So print the name of the mounted UBI volume, not just
IDs.

fs.h needs path.h, not namei.h; nfs_fs.h doesn't need it at all.
Several places in the tree needed direct include.

Kmem cache passed to constructor is only needed for constructors that are
themselves multiplexeres. Nobody uses this "feature", nor does anybody uses
passed kmem cache in non-trivial way, so pass only pointer to object.
Non-trivial places are:
arch/powerpc/mm/init_64.c
arch/powerpc/mm/hugetlbpage.c
This is flag day, yes.
