Date: Thu, 18 Nov 2010 05:05:46 -0600 From: Sonny Rao <sonnyrao@...ux.vnet.ibm.com> To: linux-scsi@...r.kernel.org Cc: Sonny Rao <sonnyrao@...ux.vnet.ibm.com>, Milton Miller <miltonm@....com>, Andrew Vasquez <andrew.vasquez@...gic.com>, linux-driver@...gic.com, "James E.J. Bottomley" <James.Bottomley@...e.de>, linux-scsi@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] [RFC] qla2xxx: Change parameter permissions in sysfs Many of the module parameter definitions in qla2xxx look like S_IRUGO|S_IRUSR which is effectively doing 0400 | 0444 which is pointless. It seems like the intention is to allow a user to change these parameters in sysfs. So this patch changes it to S_IRUGO|S_IWUSR to enable that. Most of these copied into a device-specific structure at init time, so the user would have to re-probe or re-bind the adapters for these to take effect.
