 # On the 'tile' arch, USB OHCI needs the bounce pool since tilegx will often
 # have more than 4GB of memory, but we don't currently use the IOTLB to present
 # a 32-bit address to OHCI.  So we need to use a bounce pool instead.

-# We also use the bounce pool to provide stable page writes for jbd.  jbd
-# initiates buffer writeback without locking the page or setting PG_writeback,
-# and fixing that behavior (a second time; jbd2 doesn't have this problem) is
-# a major rework effort.  Instead, use the bounce buffer to snapshot pages
-# (until jbd goes away).  The only jbd user is ext3.
