fb: fsync() method for deferred I/O flush.
There are cases when we do not want to wait on the delay for automatically
updating the "real" framebuffer, this implements a simple ->fsync() hook
for explicitly flushing the deferred I/O work. The ->page_mkwrite()
handler will rearm the work queue normally.
(akpm: nuke unneeded ifdefs, forward-delcare struct dentry)
