jffs2: Replace zero-length array with flexible-array
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

Fix directory hardlinks from deleted directories
When a directory is deleted, we don't take too much care about killing off all the dirents that belong to it — on the basis that on remount, the scan will conclude that the directory is dead anyway.
This doesn't work though, when the deleted directory contained a child directory which was moved *out*. In the early stages of the fs build we can then end up with an apparent hard link, with the child directory appearing both in its true location, and as a child of the original directory which are this stage of the mount process we don't *yet* know is defunct.
To resolve this, take out the early special-casing of the "directories shall not have hard links" rule in jffs2_build_inode_pass1(), and let the normal nlink processing happen for directories as well as other inodes.
Then later in the build process we can set ic->pino_nlink to the parent inode#, as is required for directories during normal operaton, instead of the nlink. And complain only *then* about hard links which are still in evidence even after killing off all the unreachable paths.

The variable csize in structure jffs2_tmp_dnode_info is of type uint16_t, but it is used to hold the compressed data length(csize) which is declared as uint32_t. So, when the value of csize exceeds 16bits, it gets truncated when assigned to tn->csize. This is causing a kernel BUG. Changing the definition of csize in jffs2_tmp_dnode_info to uint32_t fixes the issue.

fs/vfs/security: pass last path component to LSM on inode creation
SELinux would like to implement a new labeling behavior of newly created inodes. We currently label new inodes based on the parent and the creating process. This new behavior would also take into account the name of the new object when deciding the new label. This is not the (supposed) full path, just the last component of the path.
This is very useful because creating /etc/shadow is different than creating /etc/passwd but the kernel hooks are unable to differentiate these operations. We currently require that userspace realize it is doing some difficult operation like that and than userspace jumps through SELinux hoops to get things set up correctly. This patch does not implement new behavior, that is obviously contained in a seperate SELinux patch, but it does pass the needed name down to the correct LSM hook. If no such name exists it is fine to pass NULL.

When JFFS2 is used for large volumes, the mount times are quite long. Increasing the hash size provides a significant speed boost on the OLPC XO-1 laptop.
Add logic that dynamically selects a hash size based on the size of the medium. A 64mb medium will result in a hash size of 128, and a 512mb medium will result in a hash size of 1024.

In particular, remove the bit in the LICENCE file about contacting Red Hat for alternative arrangements. Their errant IS department broke that arrangement a long time ago -- the policy of collecting copyright assignments from contributors came to an end when the plug was pulled on the servers hosting the project, without notice or reason.
We do still dual-license it for use with eCos, with the GPL+exception licence approved by the FSF as being GPL-compatible. It's just that nobody has the right to license it differently.

[JFFS2] Improve read_inode memory usage, v2.
We originally used to read every node and allocate a jffs2_tmp_dnode_info structure for each, before processing them in (reverse) version order and discarding the ones which are obsoleted by later nodes.
With huge logfiles, this behaviour caused memory problems. For example, a file involved in OLPC trac #1292 has 1822391 nodes, and would cause the XO machine to run out of memory during the first stage of read_inode().
Instead of just inserting nodes into a tree in version order as we find them, we now put them into a tree in order of their offset within the file, which allows us to immediately discard nodes which are completely obsoleted.
We don't use a full tree with 'fragments' pointing to the real data structure, as we do in the normal fragtree. We sort only on the start address, and add an 'overlapped' flag to the tmp_dnode_info to indicate that the node in question is (partially) overlapped by another.
When the scan is complete, we start at the end of the file, adding each node to a real fragtree as before. Where the node is non-overlapped, we just add it (it doesn't matter that it's not the latest version; there is no overlap). When the node at the end of the tree _is_ overlapped, we sort it and all its overlapping nodes into version order and then add them to the fragtree in that order.
This 'early discard' reduces the peak allocation of tmp_dnode_info structures from 1.8M to a mere 62872 (3.5%) in the degenerate case referenced above.
This version of the patch also correctly rememembers the highest node version# seen for an inode when it's scanned.
