Suppose the following situation: 1. Lock a cached page 2. Change it 3. Set it dirty 4. Unlock the page
From this point, it is assumed that the kernel may write the page. How can I prevent the page from being written, even if some "sync" function is called like, for example, filemap_write_and_wait? I thought of not seting it dirty, but then what happens if the kernel is short in memory? Does it preserve the page, and so keeping the changes I did? Can the uptodate or reserved flags play any role on this? How? Keeping it locked does not work because if I need to call a sync function for the other pages (filemap_write_and_wait) it hangs.
