Yep. For the DMA zone all slab cache will be a memory pin (like ptes for highmem, but not that many people runs with 3G of ram in ptes, and I guess the ones doing it aren't normally using a mainline kernel in the first place so they're likely not running into it either). While slab cache pinning the normal zone has more probability of being reproduced on l-k in random usages. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
