Now in vfs.fixes.

@Konstantin, for some reason I keep having issues with this patch
series. It confuses b4 to no end. When I try to shazam this single patch
here using 2181767.1723665003@...thog.procyon.org.uk it pull down a 26
patch series. And with -P _ it complains that it can't find the messag
id.
