[PATCH v7 28/31] NFSv4: Open state recovery must account for file permission changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If the file permissions change on the server, then we may not be able to
recover open state. If so, we need to ensure that we mark the file
descriptor appropriately.
