From 5a7ad7f044941316dc98eda2a087a12a7a50649d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 20 Sep 2007 16:05:10 +0900 Subject: sysfs: kill sysfs_update_file() sysfs_update_file() depends on inode->i_mtime but sysfs iondes are now reclaimable making the reported modification time unreliable. There's only one user (pci hotplug) of this notification mechanism and it reportedly isn't utilized from userland. Kill sysfs_update_file().
