[patch] Support for kernel 6.0.2 (Parallel Tools 18.0.2.53077)

Hi, everyone!

You guessed it, I updated my Arch Linux and got a new kernel which is not compatible with the latest Parallels Tools. Attached is a patch to the tools, so the modules compile against kernel v6.

 

Thanks for being ahead of the game.

 

Thanks a lot @GalaxyMaster!

 

@GalaxyMaster, I tried your patch which might work but I get a lot of other errors. Could you have a look what could it be?
I use Suse aarch64 and get following errors:

Error: failed to upgrade Parallels Guest Tools!

 

actually the only line I need to fix is:
/usr/lib/parallels-tools/kmods/prl_fs/SharedFolders/Guest/Linux/prl_fs/inode.c:958:10: error: 'const struct address_space_operations' has no member named 'readpage'

What can I do here?

 

I avoidhaving kernel updates on my guest OS at the moment, by choosing to remain on 5.19.8, as that 5.18 - 19, which was the last version reported on the Arch Linux info page for parallels, as being supported. The technique for avoiding kernel upgrades is quite easy in arch linux using pacman
In the the /etc/pacman.conf (for aarch64 guest)
# Pacman won't upgrade packages in the IgnorePkg and IgnoreGroup
IgnorePkg = linux-aarch6 linux-aarch64-headers 4 linux-eos-arm-headers

The linux-eos-arm-headers comes from having the Endeavour OS add-ons to Arch linux for aarch64.

 

The kernel interface seems have been changed, so I would look at the commits touching that space and see how kernel devs updated the related pieces. Unfortunately, I am running an Intel-based Mac, so I did not encounter this particular issue and I don't have a habit to provide advice that I cannot verify myself.

 

Thank you GalaxyMaster
Your diff file also works on 18.0.1
BTW, I use arch..

 

I can confirm that the patch also works for Version 18.0.3 (53079)

 

Just an update, Parallels Desktop 18.1.0 (and its parallel-tool of course) doesn't require the patch on kernel 6.0.2
