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!
