Hi,
Is it possible to allocate and add pages to the page cache without a underlying file
system in Linux 2.4? I know that the host pointer to inode structure inside the
address_space structure can be NULL, but does this mean that we can still make use of
page cache operations like readpage or writepage if we do not back up the cache with a
file system? I am currently developing a driver that wants to make use of the page
cache, however, I want to save myself with the heavy load of kmalloc.
Any hint would be greatly appreciated.
Thanks
