From ed4570e6f08c76b5daa2aa558ae75871324077ce Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Thu, 17 Sep 2020 11:45:09 +0800 Subject: fsimpl: improve the "implements" comments As noticed by @ayushr2, the "implements" comments are not consistent, e.g. // IterDirents implements kernfs.inodeDynamicLookup. // Generate implements vfs.DynamicBytesSource.Generate. This patch improves this by making the comments like this consistently include the package name (when the interface and struct are not in the same package) and method name.
