[PATCH v3 11/11] NFS replace cross device with cross filesystem check in copy_file_range

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

 



From: Olga Kornievskaia <kolga@xxxxxxxxxx>

VFS copy_file_range was relaxed to allow for cross-device copy.
NFS code was added to support for server to server copy offload.
Add a check to disallow cross file systems copy offload, both
files are expected to be of NFS type.
