2018-08-10fs: Allow overlays to revalidate files from the upper fs.Nicolas Lacasse
Previously, an overlay would panic if either the upper or lower fs required revalidation for a given Dirent. Now, we allow revalidation from the upper file, but not the lower. If a cached overlay inode does need revalidation (because the upper needs revalidation), then the entire overlay Inode will be discarded and a new overlay Inode will be built with a fresh copy of the upper file. As a side effect of this change, Revalidate must take an Inode instead of a Dirent, since an overlay needs to revalidate individual Inodes.

2018-07-19fs: Pass context to Revalidate() function.Nicolas Lacasse
The current revalidation logic is very simple and does not do much introspection of the dirent being revalidated (other than looking at the type of file). Fancier revalidation logic is coming soon, and we need to be able to look at the cached and uncached attributes of a given dirent, and we need a context to perform some of these operations.
