Comment by Andreas Dilger [ 24/May/23 ]

James, I just noticed that the patches here are adding Ubuntu 22.04 build support for the client, but there is no entry in lustre/ChangeLog.

Could you (or Shaun or Jian) please add that to the next kernel patch you submit so that users know this is possible.

Comment by James A Simmons [ 25/May/23 ]

I reason I delayed was the lack of native fscrypt support. I need to work on one more patch to truly support 5.15 natively.

Comment by Liyi Meng [ 19/Aug/23 ]

Hi @James,  any progress on this? I am curious what is the missing bits. Maybe I can help with some testing?
