2020-03-25libata: Assign OF node to the SCSI deviceLinus Walleij1-0/+30
When we spawn a SCSI device from an ATA device in libata-scsi the SCSI device had no relation to the device tree. The DT binding allows us to define port nodes under a PATA (IDE) or SATA host controller, so we can have proper device nodes for these devices. If OF is enabled, walk the children of the host controller node to see if there is a valid device tree node to assign. The reg is used to match to ID 0 for the master device and ID 1 for the slave device. The corresponding device tree bindings have been accepted by the device tree maintainers.

2020-03-07io_uring: fix lockup with timeoutsPavel Begunkov1-0/+1
There is a recipe to deadlock the kernel: submit a timeout sqe with a linked_timeout (e.g. test_single_link_timeout_ception() from liburing), and SIGKILL the process. Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it during io_put_free() to cancel the linked timeout. Probably, the same can happen with another io_kill_timeout() call site, that is io_commit_cqring(). Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
