[XFS] Long btree pointers are still 64 bit on disk
On 32 bit machines with CONFIG_LBD=n, XFS reduces the
in memory size of xfs_fsblock_t to 32 bits so that it
will fit within 32 bit addressing. However, the disk format
for long btree pointers are still 64 bits in size.
The recent btree rewrite failed to take this into account
when initialising new btree blocks, setting sibling pointers
to NULL and checking if they are NULL. Hence checking whether
a 64 bit NULL was the same as a 32 bit NULL was failingi
resulting in NULL sibling pointers failing to be detected
correctly. This showed up as WANT_CORRUPTED_GOTO shutdowns
in xfs_btree_delrec.
Fix this by making all the comparisons and setting of long
pointer btree NULL blocks to the disk format, not the
in memory format. i.e. use NULLDFSBNO.

There are several tests for #ifndef HAVE_FORMAT32, but
this is never defined anywhere so it is always the default
behavior; just remove the ifndef goop.

dlm_posix_get fills out the relevant fields in the file_lock before
returning when there is a lock conflict, but doesn't clean out any of
the other fields in the file_lock.
When nfsd does a NFSv4 lockt call, it sets the fl_lmops to
nfsd_posix_mng_ops before calling the lower fs. When the lock comes back
after testing a lock on GFS2, it still has that field set. This confuses
nfsd into thinking that the file_lock is a nfsd4 lock.
Fix this by making DLM reinitialize the file_lock before copying the
fields from the conflicting lock.

We should use the original copy of the file_lock, fl, instead
of the copy, flc in the lockd notify callback. The range in flc has
been modified by posix_lock_file(), so it will not match a copy of the
lock in lockd.

Since ->acquire_dquot and ->release_dquot callbacks aren't called under
dqptr_sem anymore, we don't have to start a transaction and obtain locks
so early. So we can just remove all this complicated stuff.

Some sysfs binary files don't like having 0 passed to them as a size.
Fix this up at the root by just returning to the vfs if userspace asks
us for a zero sized buffer.
Thanks to Pavel Roskin for pointing this out.

without a journal, the "circular indirect block" sanity test was

Recently we have quite a few kerneloops reports about dereferencing a NULL
if_data in the attribute fork. From looking over the code this can only
happen if we pass a 0 size argument to xfs_iformat_local. This implies some
sort of corruption and in fact the only mailinglist report about this from
earlier this year was after a powerfail presumably on a system with write
cache and without barriers.
Add a quick sanity check for the attr fork size in xfs_iformat to catch
these early and without an oops.

Currently the bad_features2 fixup and the alignment updates in the superblock
are skipped if we mount a filesystem read-only. But for the root filesystem
the typical case is to mount read-only first and only later remount writeable
so we'll never perform this update at all. It's not a big problem but means
the logs of people needing the fixup get spammed at every boot because they
never happen on disk.

We can have both a user and a group/project dquot locked at the same time,
as long as the user dquot is locked first. Tell lockdep about that fact
by making the group/project dquots a different lock class.

xfs_dqlock2 locks two xfs_dquots, which is fine as it always locks the
dquot with the lower id first. Use mutex_lock_nested to tell lockdep

The compat version of the attrmulti ioctl needs to ask for and then
later release write access to the mount just like the native version,
otherwise we could potentially write to read-only mounts.

Open by handle just grabs an inode by handle and then creates itself
a dentry for it. While this works for regular files it is horribly
broken for directories, where the VFS locking relies on the fact that
there is only just one single dentry for a given inode, and that
these are always connected to the root of the filesystem so that
it's locking algorithms work (see Documentations/filesystems/Locking)
Remove all the existing open by handle code and replace it with a small
wrapper around the exportfs code which deals with all these issues.
At the same time we also make the checks for a valid handle strict
enough to reject all not perfectly well formed handles - given that
we never hand out others that's okay and simplifies the code.
