Subject: Reiser4: remove simple_prepare_write usage
From: Laurent Riffard <laurent.riffard@xxxxxxx>
Reiser4 can't be built as a module when EXPORT_UNUSED_SYMBOL is not set.
It's broken because reiser4_write_extent is calling
simple_prepare_write() and commit
4e02ed4b4a2fae34aae766a5bb93ae235f60adb8 scheduled it for unexporting.
