Thanks. pte_offset_map, if I recall correctly, can map a high-memory page table into the kernel address space. Later pte_unmap removes the mapping. pte_offset doesn't do that. Check the macro definitions in include/asm/pgtable.h, but I don't know what pte_offset_atomic does. -- Ed L Cashin <ecashin@xxxxxxxxxx> -- Kernelnewbies: Help each other learn about the Linux kernel.
