Message-ID: <40B16736.6090303@easyco.com> (raw)
I pulled some more information (if I did it correctly) from the first stack dump from the first
__alloc_pages error log.

If I am reading this correctly, the system was ...
in an interrupt
processing some TCP select(...) stuff
asking for a page
doing a zone rebalance
trying to shrink cache
and interrupted again
by the ethernet driver
which wanted to allocate an skb
which wanted a page
Thus __alloc_pages appears to be called recursively, with the 2nd call during a rebalance in the
first one and both calls non-interuptable (on interrupts). Is this allowable?
