If anyone has any objections, please let me know. ------------------ From: Pu Lehui [ Upstream commit 2294073dce32af8535e9d4a32e1efdeea35c1786 ] Support vmtest to use local rootfs image generated by [0] that is consistent with BPF CI. Now we can specify the local rootfs image through the `-l` parameter like as follows: vmtest.sh -l ./libbpf-vmtest-rootfs-2024.08.22-noble-amd64.tar.zst -- ./test_progs Meanwhile, some descriptions have been flushed.
