[PATCH v3 7/9] vfs: Remove copy_file_range mountpoint checks

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

 



I still want to do an in-kernel copy even if the files are on different
mountpoints, and NFS has a "server to server" copy that expects two
files on different mountpoints.  Let's have individual filesystems
implement this check instead.
