Subject: vm_operations .. how to unmap?
Date: Fri, 30 Aug 2002 16:25:24 -0700	[thread overview]
Message-ID: <02cd01c2507c$84ec9860$9e10a8c0@IMRANPC> (raw)

Hi,
I am exporting kernel memory to user processes using mmap() entry point of
my driver. Now, when the user calls unmap(), I would like to deallocate the
pages which I allocated at mmap() time. How can I do that? unmap() entry
point is not provided by vm_operations structure in mm.h file.
I will really appreciate any suggestion/guidance.

Thanks,
Imran.
