Subject: Changes in vm_operations_struct 2.2.x => 2.4.x
Date: Fri, 03 Aug 2001 10:01:22 +0200 [thread overview]
Message-ID: <3B6A5A52.73D0DC12@scs.ch> (raw)
Hi,
Playing around with kernel memory allocated by a module and mmap()ed by a user space process, I noticed that in the 2.4.x kernel many of the 2.2.x vm_operation_struct
fields have gone. In particular there is no unmap operation any more. Is there any way for a driver to get notified when the user space process mapping memory exported by
the driver unmaps parts of that memory (as far as I know, the close operation is invoked when the entire memory is unmapped)? Does anyone know the reason why the number of
operations in vm_operation_struct has been reduced?
regards
Martin
