+Subject: ecryptfs: read on a directory should return EISDIR if not supported
+
+From: Andy Whitcroft <apw@canonical.com>
+
+commit 323ef68faf1bbd9b1e66aea268fd09d358d7e8ab upstream.
+
+read() calls against a file descriptor connected to a directory are
+incorrectly returning EINVAL rather than EISDIR:
+
+ [EISDIR]
+ [XSI] [Option Start] The fildes argument refers to a directory and the
+ implementation does not allow the directory to be read using read()
+ or pread(). The readdir() function should be used instead. [Option End]
+
+This occurs because we do not have a .read operation defined for
+ecryptfs directories. Connect this up to generic_read_dir().
