H A Dkcopyd.rst5 Kcopyd provides the ability to copy a range of sectors from one block-device
10 to set aside for their copy jobs. This is done with a call to

17 the source and destinations of the copy. Each io_region indicates a
19 of the copy is given as one io_region structure, and the destinations of the
20 copy are given as an array of io_region structures::
28 To start the copy, the user calls kcopyd_copy(), passing in the client
30 completion callback routine, and a pointer to some context data for the copy::
39 When the copy completes, kcopyd will call the user's completion routine,
