And PageMappedToDisk()?

I disagree. For the most part weird capsage is wrong, but this is readable.
Whilst it could make it page_fs_misc() instead, that'd be against the style of
the rest of the file, though maybe you want to go through and change all of
that too.

Maybe you'd prefer bPageFsMisc()? :-)

Actually, all these functions should really be called something like
IsPageXxxx() to note they're asking a question rather than giving a command.

> PageMisc would look less ugly

I disagree again. I don't think PageFsMisc() is particularly ugly or
unreadable; and it makes it a touch more likely that someone reading code that
uses it will notice that it's a miscellaneous flag specifically for filesystem
use (you can't rely on them going and looking in the header file for a
comment).

There should be a comment as well, I suppose. I'll amend the patch for Andrew.

All this should also be documented in Documentation/ somewhere too, I suppose.
