From ecb3908046ce9ce7feb44e2c2cf77ccdbe231f70 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Thu, 27 Sep 2007 13:41:17 -0700 Subject: [PATCH] pci: write file size to inode on proc bus file write When a /proc/bus/pci file is written to, the size of that PCI device's configuration space must be written to the inode. Otherwise, it is possible for the file to specify a size of 0 on stat if a task is holding the same file open.
