We set xfs project quota with overlayfs for docker container. When I enter into the container and run the command 'df -ih', the 'IFree' and 'IUsed' are uncorrect: #df -ih Filesystem Inodes IUsed IFree IUse% Mounted on overlay 1000 -235M 235M - / So I want to fix this flaw, and this is very meaningful for our applications.
