Filesystems like xfs, btrfs, gfs2 and ocfs2 handle quotas internally and do not need external quotacheck/quotaon services. When usrquota or grpquota mount options are used in fstab for these filesystems, generator_hook_up_quotacheck() falls through to the !fstype_needs_quota() branch and emits a misleading warning that quotas are "not supported" when they actually work fine — the kernel handles them internally. Add fstype_has_internal_quota() to return early with a debug message, and adopt a tri-state return convention so the caller skips quotaon when quotacheck was not needed. The buggy code path was introduced in #24824 and #24880. Co-developed-by: Claude Opus 4.6 <noreply@anthropic.com>
