So this means that I need to use try_to_release_page() on only those
mapped pages that have page->buffer non-null. Otherwise releasepage
functions of the address space crash. And if I have to return a mapped
page to the freelist that have page->buffer null, i just have to do
__remove_inode_page. I am speaking in the context of 2.4 kernel. Am I
right.
Thanks a lot,
Raghu
