Using direct IO with ecryptfs and similar stackable file systems

Does "ecryptfs" support direct I/O? In general, how can a "stackable" file system, that modifies buffer provided by user support direct I/O?

Solution

  • ecryptfs does not support direct I/O.

    There is no implementation of direct_IO() callback in ecryptfs address_space_operations.
