Subject: Processes attached to shared memory

Given a struct shmid_kernel, is it possible to find each
process/task_struct which is attached to the shared memory?

I have been trying to use find_get_pages(shmid->shm_file->f_mapping, ...)
along with rmap_walk(...). But what I have come up with seems a little
convoluted and also triggers "BUG: scheduling while atomic" errors.
