You meant passing > GFP_KERNEL or GFP_NOFS based on errok right ? No, I meant passing GFP_NOFS always. Currently, GFP_NOFS is used in all the cases (noone uses GFP_KERNEL variant) and GFP_KERNEL can really be used only when we do not hold other filesystem locks (as GFP_KERNEL allocation can recurse back into filesystem to reclaim memory). So using GFP_KERNEL would need more auditting and is a separate issue anyway. > > Also your patch series should be bisectable - that means it must compile > > and run after any of the patches.
