Applying MSD patches doesn't work

[srepac]

When running the installer script, applying kernel patch for MSD doesn't work.

Here's the extracted output during install:

-> Apply patches using /root/kvmd-armbian/patches/custom/old-kernel-msd/*.patch files
error: patch failed: kvmd/aiohelpers.py:40
error: kvmd/aiohelpers.py: patch does not apply
error: patch failed: kvmd/plugins/msd/otg/__init__.py:241
error: kvmd/plugins/msd/otg/__init__.py: patch does not apply
-> Add otgmsd unlock link
-> Add sudoer
-> Apply old kernel msd patch done.

As you can see, none of the patches got applied. Also, after resize root partition, create/format MSD partition as ext4, then enabling MSD by deleting

    msd:
        type: disabled

entries in /etc/kvmd/override.yaml and rebooting the orange pikvm, I also updated /etc/fstab to the following and made sure /var/lib/kvmd/msd is mounted properly.

/dev/mmcblk0p1 / ext4 defaults,noatime,commit=600,errors=remount-ro 0 1
/dev/mmcblk0p2 /var/lib/kvmd/msd  ext4  nodev,nosuid,noexec,ro,errors=remount-ro,data=journal,X-kvmd.otgmsd-root=/var/lib/kvmd/msd,X-kvmd.otgmsd-user=kvmd  0 0
tmpfs /tmp tmpfs defaults,nosuid 0 0

As a result, MSD menu shows up in webui, but mass storage drive shows offline due to an error:

At this point in time, MSD is not supported working on kvmd-armbian.

This msd patch only for old linux kernel, maybe new version of kvmd makes my patch not working, I will try fix it.

I don't believe the kernel patch for forced_eject functionality has been applied to armbian kernel. Here's the link to the actual patch

https://github.com/pikvm/packages/blob/master/packages/linux-rpi-pikvm/2002-usb-gadget-f_mass_storage-forced-eject.patch
