From 2f5947dfcaecb99f2dd559156eecbeb7b95e4c02 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 24 Jul 2019 09:24:49 +0200 Subject: Documentation: move Documentation/virtual to Documentation/virt Renaming docs seems to be en vogue at the moment, so fix on of the grossly misnamed directories. We usually never use "virtual" as a shortcut for virtualization in the kernel, but always virt, as seen in the virt/ top-level directory. Fix up the documentation to match that.
