Move that comment to the head of the function. i.e.:
/*
* We support two different versions of the fs_quota_stat structure
* here. If the version is FS_QSTAT_VERSION, then there is no
* separate project quota fields, and so we write project quota
* information into the group quota fields. With FS_QSTAT_VERSION_2,
* there is a separate project quota field so we can use that
* instead to pass both group and project quota back to user space
* in the one call.
*/
Cheers,
Dave.
