I just discovered an oddity in 2.2.18pre15. When ioremap() is used to map reserved pages (of real RAM), it does not increment the "count" field for the page it remaps (i.e. page->count). However, when you call iounmap on that memory, that function decrements page->count. Since the count was originally zero, it gets decremented to -1, and that's when things start to go bad. I get the feeling that if I remap reserved memory, I'm not supposed to ever unmap it. But that means that my driver will have a memory leak. Can someone help me out? -- Timur Tabi - [EMAIL PROTECTED] Interactive Silicon - http://www.interactivesi.com When replying to a mailing-list message, please direct the reply to the mailing list only.
