From 270b5ac2151707c25d3327722c5badfbd95945bc Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 12 Apr 2013 02:48:30 +0100 Subject: proc: Add proc_mkdir_data() Add proc_mkdir_data() to allow procfs directories to be created that are annotated at the time of creation with private data rather than doing this post-creation. This means no access is then required to the proc_dir_entry struct to set this.
