Are there deployments that are updating to new versions of U-Boot that require NFSv1 though? > We are shipping devices right now which are based on vxworks 5.

So they're using a 25 year old version of vxworks with the latest version of U-Boot? And vxworks supports only NFSv1, and not NFSv2, which has been out since 1989 and was the first version that even Sun supported publicly? > So I know It is a quite specific use case but we want to upstream most > of our downstream > patches. > > Btw. if this patch series will not land does this mean NFSv2 will die too > soon? At least NFSv2 is supported to some degree whereas it seems NFSv1 is something that's special to vxworks, how are people supposed to test it? I don't see any tests in your patchset and I'm not sure how it's useful outside of the legacy vxmworks use case. At the very least this should be behind a Kconfig option. Peter
