Subject: about mmap with MAP_SHARED in jffs2
Date: Fri, 18 Nov 2005 14:35:45 +0800 [thread overview]
Message-ID: <006201c5ec0a$4f2610d0$9d02a8c0@image> (raw)
Hi,
Currently jffs2 not support mmap with MAP_SHARED. Is it possible to implement it? What's the drawback? If it's possible, what shoould we do? I changed .mmap from generic_file_readonly_mmap to generic_file_mmap
but system crash when I write to mmaped buffer and unmap. Do I need a special writepage?
Best regards!
