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.

2018-07-18Fix lock-ordering violation in Create by logging BaseName instead of FullName.Nicolas Lacasse
Dirent.FullName takes the global renameMu, but can be called during Create, which itself takes dirent.mu and dirent.dirMu, which is a lock-order violation: Dirent.Create d.dirMu.Lock d.mu.Lock Inode.Create gofer.inodeOperations.Create gofer.NewFile Dirent.FullName d.renameMu.RLock We only use the FullName here for logging, and in this case we can get by with logging only the BaseName. A `BaseName` method was added to Dirent, which simply returns the name, taking d.parent.mu as required. In the Create pathway, we can't call d.BaseName() because taking d.parent.mu after d.mu violates the lock order. But we already know the base name of the file we just created, so that's OK. In the Open/GetFile pathway, we are free to call d.BaseName() because the other dirent locks are not held. PiperOrigin-RevId: 205112278 Change-Id: Ib45c734081aecc9b225249a65fa8093eb4995f10
