Acked-by Andrea Arcangeli <[email protected]>Only one improvement possible, the
smp_wmb()could have been put underCONFIG_TRANSPARENT_HUGEPAGEsomehow. No difference for x86-64 though.
I thought it would be better to serialize it with get_page_unless_zero() in general, but OK, As the changelog says I didn't find another problematic caller, so please see v2. I preserved your ack, thanks.
And I would like to know your opinion about other changes I sent ;)
