From 0f4238958d28044b335644b69df6071cdb04b5ce Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 20 Mar 2008 20:47:52 -0500 Subject: [SCSI] sysfs: make group is_valid return a mode_t We have a problem in scsi_transport_spi in that we need to customise not only the visibility of the attributes, but also their mode. Fix this by making the is_visible() callback return a mode, with 0 indicating is not visible. Also add a sysfs_update_group() API to allow us to change either the visibility or mode of the files at any time on the fly.
