What would be the downside of simply always inhereiting the project ID
from the parent directory? I see that if the flag is not set, the
project id will be 0 instead. I'm not sure when that would actually
be desirable.
To the extent that the project ID is designed to implement a quota
over a directory extent, the fact that the owner can clear the
EXT4_PROJINHERET_FL and then arrange to have the quota charged to
project 0 seems to me to be a bug, not a feature.
Can you explain what your intended use case for this flag might be?
Thanks,
