.SH DESCRIPTION
Turn off quotas for an XFS filesystem.
.P
As with
.BR Q_XQUOTAON (2const),
XFS filesystems expect a pointer to an
.I \%unsigned\~int
that specifies whether quota accounting and/or limit enforcement
need to be turned off
(using the same flags as for
.BR Q_XQUOTAON (2const)).
.P
This operation requires privilege
.RB ( CAP_SYS_ADMIN ).
.SH RETURN VALUE
See
.BR quotactl (2).
.SH ERRORS
See
.BR quotactl (2).
.SH STANDARDS
Linux.
