Subject[PATCH v2 0/3] io_uring: add splice(2) support
Date
Probably, not the fastets implementation, but I'd need to stir up/duplicate
splice.c bits to do it more efficiently.

note: rebase on top of the recent inflight patchset.

v2:
- u32 len and SQE layout changes (Jens)
- output file is in sqe->fd for automatic hash_reg_file support
- handle unbound_nonreg_file for the second fd
- file leaks fixed with REQ_F_NEED_CLEANUP
- place SPLICE_F_FD_IN_FIXED in splice flags (Jens)
- loff_t* -> loff_t, -1 means not specified offset


Pavel Begunkov (3):
splice: make do_splice public
io_uring: add interface for getting files
io_uring: add splice(2) support
