Message-ID: <20200303202054.gsosv7fsx2ma3cic@linutronix.de> (raw)
In-Reply-To: <20200303175910.ichnkjkgmz5y2ipb@linutronix.de>
The proc file `compact_unevictable_allowed' should allow 0 and 1 only,
the `extra*' attribues have been set properly but without
proc_dointvec_minmax() as the `proc_handler' the limit will not be
enforced.
Use proc_dointvec_minmax() as the `proc_handler' to enfoce the valid
specified range.
