I believe it is already done for some other filesystems like ocfs2. > - add library interfaces for doing the quota changes to libext2fs (or a new very simple library) and have the quota tools link to that instead of interfacing to the kernel directly > I have already sent patches to add a new quota library in e2fsprogs (this library too is majorly based on the current quota tools). With this, e2fsck can scan and fix quota files and tune2fs/mke2fs can be used to turn on/off the new quota feature.
