Pushed updated series based on your vfs.git#for-ovl branch to the overlayfs-next tree. There's the additional patch dealing with nr_files accounting (will post for review shortly). That one has a trivial conflict with the mount series, otherwise merges cleanly with viro/vfs.git#for-next. I like the call_with_creds() idea. I didn't realize that override_creds()/revert_creds() can be quite heavyweight due to doing (unnecessary in this case) refcounting. Could use call_with_creds() in overlayfs too, since we hold ref on ofs->creator_cred for the lifetime of the filesystem. Thanks, Miklos
