Hi there,
We are aware that the shared memory structure in the IPC array, has a
pointer to the inode which has a cyclic link list of vm_area_structs of all
processes that have attached to that shared region. Is this array
(vm_next_share or vm_next_prev) really used apart from update_mmu_cache or
vmtruncate_list??
Also when and where are the shmem_file_operations like shmem_file_read,
shmem_file_map, etc invoked?? Are they by any chance related to accessing
the shared memory used in shmget, shmat??? Or shm_open, shm_link??
Thanks & Regards,
MAASK
