Do we completely understand the root cause, in terms of which commit
broken the mm/page-writeback.c code we were depending on? And if so,
what of the code in mm/page-writeback.c? Does anyone else use it?
Can anyone sanely use it?
And am I right in assuming that this only applies to 2.6.29-rcX
kernels, and is not needed for 2.6.28 or earlier kernels?
I hadn't yet pushed it out because I needed time to understand all of
these issues, hence these questions....
