# The _emodinst_ target allows us to install an out-of-tree module without
# running depmod. This is useful because we only need to run depmod once after
# we installed all out-of-tree modules. Also, we can't have multiple instances
# of scripts/depmod.sh run in parallel because that script is not safe to be
# invoked multiple times in parallel.
# Note that the _emodinst_ target is going away with Linux 5.13, so we have to
# find a different solution then.
