May be one can just call try_to_unmap() from shmem_writepage()?

That sounds much cleaner.  But I've not yet found what tree your
p12-dont-unmap-on-pageout.patch applies to, so cannot judge it.

Whole
ftp://ftp.namesys.com/pub/misc-patches/unsupported/extra/2004.02.04/
applies to the 2.6.2-rc2.

I just updated p12-dont-unmap-on-pageout.patch in-place.

 

Sure, I can give this a try. It makes sense.
