vfs: implement subset of copy_file_range() #1308

Closed wkozaczuk closed 8 months ago

wkozaczuk commented 8 months ago

This patch implements a subset of copy_file_range() that is needed by the GNU cp utility to function.

The implementation delegates to sendfile() and accepts calls with off_out equal to 0 only.
