OK, now I get the idea Still there could be some edge cases - like hibernating filesystem cache as a part of kernel-related RAM , then shutting down, booting Linux, changing the filesystem and then booting windows (which does not know that filesystem pages were changed from outside and working with obsolete copy from cache). This one is a non-issue actually, because Linux ntfs-3g driver deletes hiberfil.sys when mounting NTFS partition in R/W mode, but there could be other edge cases like this one.
