From fb5f51c7425ebc808d91329257cbc963e2421368 Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Thu, 24 Nov 2016 08:03:41 +1100 Subject: vfs: change d_manage() to take a struct path For the autofs module to be able to reliably check if a dentry is a mountpoint in a multiple namespace environment the ->d_manage() dentry operation will need to take a path argument instead of a dentry.
