From: Andy Whitcroft <[email protected]>
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().
