Hi. I read somewhere that seemed authoritative (unfortunately I forget where) that you could use the rmap stuff to get both the mm_struct pointer and the task_struct pointer associated with a PTE given that PTE. I see in mm/rmap.c:try_to_unmap_one that you can use ptep_to_mm to get the mm. I think it's pretty neat: the mm pointer is hidden in the mapping field of the page struct describing the page where the pte lives. How can you get the task_struct, though? There's nothing in include/asm-generic/rmap.h:pgtable_add_rmap that stores the task struct pointer anywhere, and I don't see a way to get the task struct given an mm or the vmas hanging off it. -- --Ed L Cashin | PGP public key: ecashin@uga.edu | http://noserose.net/e/pgp/ -- Kernelnewbies: Help each other learn about the Linux kernel.
