Subject: fs/notify: don't show f_handle if exportfs_encode_inode_fh failed
From: Andrey Vagin <avagin@xxxxxxxxxx>
commit 7e8824816bda16bb11ff5ff1e1212d642e57b0b3 upstream.
Currently we handle only ENOSPC. In case of other errors the file_handle
variable isn't filled properly and we will show a part of stack.
