msync & MS_INVALIDATE question
The man page I have for msync(MS_INVALIDATE) says it should invalidate
all other mappings. I.e. get all other mappings.
The implementation does something quite different, that is related to
only the present mapping.
Was this a pure documentation bug. Was MS_INVALIDATE not implemented
correctly because of no reverse maps? Or is something else going on
here?
I know in the context of MAP_SHARED invalidating other mappings seems
like a reasonable proposition.
