From 933287da750edefbf0f449750fd67b4fc6c10013 Mon Sep 17 00:00:00 2001 From: Martin Brandenburg Date: Sat, 30 Jan 2016 13:46:54 -0500 Subject: orangefs: Implement inode_operations->permission(). Thus d_revalidate is not obliged to check on as much, which will eventually lead the way to hammering the filesystem servers much less.
