If we somehow end up with a filesystem that has fewer free blocks than
the blocks set aside to avoid ENOSPC deadlocks, it's possible that the
free space calculation in xfs_reserve_blocks will spit out a negative
number (because percpu_counter_sum returns s64).  We fail to notice
this negative number and set fdblks_delta to it.  Now we increment
fdblocks(!) and the unsigned type of m_resblks means that we end up
setting a ridiculously huge m_resblks reservation.

Avoid this comedy of errors by detecting the negative free space and
returning -ENOSPC.

In commit e89c0413 ("xfs: implement the GETFSMAP ioctl") we
created the ability to obtain empty transactions.  These transactions
have no log or block reservations and therefore can't modify anything.
Since they're also NO_WRITECOUNT they can run while the fs is frozen,
so we don't need to WARN_ON about that usage.

When a corrupt inode is detected during xfs_iflush_cluster, we can
get a shutdown ASSERT failure like this:

Essentially, xfs_iflush_abort() has been called twice on the
original inode that that was flushed. This happens because the
inode has been flushed to teh buffer successfully via
xfs_iflush_int(), and so when another inode is detected as corrupt
in xfs_iflush_cluster, the buffer is marked stale and EIO, and
iodone callbacks are run on it.

Running the iodone callbacks walks across the original inode and
calls xfs_iflush_abort() on it. When xfs_iflush_cluster() returns
to xfs_iflush(), it runs the error path for that function, and that
calls xfs_iflush_abort() on the inode a second time, leading to the
above assert failure as the inode is not flush locked anymore.

This bug has been there a long time.

The simple fix would be to just avoid calling xfs_iflush_abort() in
xfs_iflush() if we've got a failure from xfs_iflush_cluster().
However, xfs_iflush_cluster() has magic delwri buffer handling that
means it may or may not have run IO completion on the buffer, and
hence sometimes we have to call xfs_iflush_abort() from
xfs_iflush(), and sometimes we shouldn't.

After reading through all the error paths and the delwri buffer
code, it's clear that the error handling in xfs_iflush_cluster() is
unnecessary. If the buffer is delwri, it leaves it on the delwri
list so that when the delwri list is submitted it sees a shutdown
fliesystem in xfs_buf_submit() and that marks the buffer stale, EIO
and runs IO completion. i.e. exactly what xfs+iflush_cluster() does
when it's not a delwri buffer. Further, marking a buffer stale
clears the _XBF_DELWRI_Q flag on the buffer, which means when
submission of the buffer occurs, it just skips over it and releases
it.

IOWs, the error handling in xfs_iflush_cluster doesn't need to care
if the buffer is already on a the delwri queue or not - it just
needs to mark the buffer stale, EIO and run completions. That means
we can just use the easy fix for xfs_iflush() to avoid the double
abort.

When the inode is in extent format, it can't have more extents that
fit in the inode fork. We don't currenty check this, and so this
corruption goes unnoticed by the inode verifiers. This can lead to
crashes operating on invalid in-memory structures.

Attempts to access such a inode will now error out in the verifier
rather than allowing modification operations to proceed.

Instead of using xfs_bmapi_read to find delalloc extents and then punch
