What would one be looking for? I don't know what the sideeffects of update_mmu_cache() might be. It looks to be the same as do_no_page() though: the update_mmu_cache() is the last substantive thing which happens in the fault or the syscall. Yes, this is what I was talking about, making sure do_file_page()'s return path isn't doing a update_mmu_cache() call already.
I don't believe this is an error (to do it twice for the same fault) but it would be superfluous. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
