I think this should be split into two patches and go first in the series: 1) remove all instances but shmem and generic_file_vm_ops given that remap_file_pages already doesn't work on anything that has a backing store and all these are dead 2) kill the method and make the syscall call generic_file_remap_pages directly as this is a core VM feature. These two should go first because they make sense even if we can't actually go with the emulation yet. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
