why using the "vsock" subdir?

IIUC you were inspired by selftests/Makefile, but it installs under
$(INSTALL_PATH)/kselftest/ the scripts used by the main one
`run_kselftest.sh`, which is installed in $(INSTALL_PATH instead.
So in this case I would install everything in $(INSTALL_PATH).

WDYT?

I agree.

Also from selftests/Makefile, what about using the ifdef instead of
using $(abspath .) as default place?

I mean this:

install: all
ifdef INSTALL_PATH
...
else
$(error Error: set INSTALL_PATH to use install) endif

Is the following looks good to you?

# Avoid conflict with INSTALL_PATH set by the main Makefile
VSOCK_INSTALL_PATH ?=
INSTALL_PATH := $(VSOCK_INSTALL_PATH)

I'm not a super Makefile expert, but why do we need both VSOCK_INSTALL_PATH and INSTALL_PATH?

install: all
ifdef INSTALL_PATH
mkdir -p $(INSTALL_PATH)
install -m 744 vsock_test $(INSTALL_PATH)
install -m 744 vsock_perf $(INSTALL_PATH)
install -m 744 vsock_diag_test $(INSTALL_PATH)
install -m 744 vsock_uring_test $(INSTALL_PATH)
else
$(error Error: set INSTALL_PATH to use install)
Endif

Thanks,
Peng.

Thanks,
