From 9a6edb60ec10d86b1025a0cdad68fd89f1ddaf02 Mon Sep 17 00:00:00 2001 From: Ralph Campbell Date: Thu, 6 May 2010 17:03:25 -0700 Subject: IB/core: Allow device-specific per-port sysfs files Add a new parameter to ib_register_device() so that low-level device drivers can pass in a pointer to a callback function that will be called for each port that is registered in sysfs. This allows low-level device drivers to create files in /sys/class/infiniband//ports// without having to poke through the internals of the RDMA sysfs handling. There is no need for an unregister function since the kobject reference will go to zero when ib_unregister_device() is called.
