From 3c70b8eeda596069258772afabf2ab0b1aa017f0 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Tue, 1 Oct 2013 16:41:22 +0200 Subject: fuse: don't check_submounts_and_drop() in RCU walk If revalidate finds an invalid dentry in RCU walk mode, let the VFS deal with it instead of calling check_submounts_and_drop() which is not prepared for being called from RCU walk.
