It sounds like this depends on https://git.kernel.org/pub/s= cm/fs/fscrypt/linux.git/log/?h=3Dwrapped-keys-v7, but actually a version of= it that you've rebased, which I don't have access to. > Without being able to apply your patchset, I can't properly review it. > --> As for the fscrypt patches, > I have not changed much functionally from the v7 patch, just merge = conflicts. > I will update this thread once I figure out a git location. >=20 Any update on this?
