Hello, what is the difference between uvm_unmap() and uvm_deallocate()?
It does not become clear to me from what is written in uvm_map(9):
uvm_unmap() removes a valid mapping, from start to end, in map map, which
must be unlocked.
uvm_deallocate() deallocates kernel memory in map map from address start
to start + size.
uvm_deallocate() is used e.g. in sysv_shm.c, in which case I would
have expected uvm_unmap().
Thanks,
Stephan
