Christoph Hellwig 070ecdca54 xfs: skip writeback from reclaim context 
Allowing writeback from reclaim context causes massive problems with stack
overflows as we can call into the writeback code which tends to be a heavy
stack user both in the generic code and XFS from random contexts that
perform memory allocations.

Follow the example of btrfs (and in slightly different form ext4) and refuse
to write out data from reclaim context.  This issue should really be handled
by the VM so that we can tune better for this case, but until we get it
sorted out there we have to hack around this in each filesystem with a
complex writeback path.
