Now that we write back all metadata either synchronously or through the AIL
we can simply implement metadata freezing in terms of emptying the AIL.
The implementation for this is fairly simply and straight-forward: A new
routine is added that increments a counter that tells xfsaild to not stop
until the AIL is empty and then waits on a wakeup from
xfs_trans_ail_delete_bulk to signal that the AIL is empty.
As usual the devil is in the details, in this case the filesystem shutdown
code. Currently we are a bit sloppy there and do not continue ail pushing
in that case, and thus never reach the code in the log item implementations
that can unwind in case of a shutdown filesystem. Also the code to
abort inode and dquot flushes was rather sloppy before and did not remove
the log items from the AIL, which had to be fixed as well.
Also treat unmount the same way as freeze now, except that we still keep a
synchronous inode reclaim pass to make sure we reclaim all clean inodes, too.
As an upside we can now remove the radix tree based inode writeback and
xfs_unmountfs_writesb.

Sorry for the empty email.
This series hangs my test boxes. This patch is the first indication of
the hang. Reboot, and remove patch 4 and the test are successful.
The machine is still responsive. Only the SCRATCH filesystem from the
test suite is hung.
Per Dave's observation, I added a couple inode reclaims to this patch
and the test gets further (hangs on run 9 of test 068 rather than run 3).
The back traces are from a Linux 3.4-rc2 kernel with just patches 0-4 of
this series applied. This traceback does not have extra inode reclaims.
The hang is in test 068. I did an ls and sync to the filesystem, so I
included their tracebacks as well. live system.
I have looked at the remaining patches in the series, but have not
reviewed them because they depend on this patch...
--Mark.
