With this: git-ls-tree -d HEAD -- drivers/net/ shows only immediate subtrees of drivers/net. git-ls-tree -d -t HEAD -- drivers/net/ shows drivers, drivers/net and immediate subtrees of drivers/net. git-ls-tree -d -r HEAD -- drivers/net/ shows drivers, drivers/net and all subtrees of drivers/net (but not blobs).
