[PATCH v1 7/9] sysctl: Fixes scsi_logging_level bounds
Posted by nicolas.bouchinet@clip-os.org 1 year ago
From: Nicolas Bouchinet <nicolas.bouchinet@ssi.gouv.fr>

Bound scsi_logging_level sysctl writings between SYSCTL_ZERO
and SYSCTL_INT_MAX.

The proc_handler has thus been updated to proc_dointvec_minmax.
