The busyloop in xfs_quiesce_attr which waits for all active transactions
to finish is supposed to fix this issue.

Note that XFS traditionally expects a two stage freeze process where
we first freeze new VFS-level writes, then flush the caches and then
stop transactions, wait for them to finish and do the remainder of
the freeze process, but I really messed that process up when moving
the sequence to generic code.  Funnily enough it seems to work
neverless.
