* block: simplify blkdev_nr_zonesChristoph Hellwig2019-12-034-23/+12
| | | | | | | | | | Simplify the arguments to blkdev_nr_zones by passing a gendisk instead of the block_device and capacity. This also removes the need for __blkdev_nr_zones as all callers are outside the fast path and can deal with the additional branch.

* null_blk: fix zone size paramter checkDamien Le Moal2019-12-031-7/+12
| | | | | | | | | | For zoned=1 mode, the zone size must be a power of 2. Check this not only when the zone size is specified during modprobe, but also when creating a zoned null_blk device using configfs.

* block: optimise bvec_iter_advance()Pavel Begunkov2019-12-031-12/+10
| | | | | | | | | | | | | | | | bvec_iter_advance() is quite popular, but compilers fail to do proper alias analysis and optimise it good enough. The assembly is checked for gcc 9.2, x86-64. - remove @iter->bi_size from min(...), as it's always less than @bytes. Modify at the beginning and forget about it. - the compiler isn't able to collapse memory dependencies and remove writes in the loop. Help it by explicitely using local vars.

| | | | | | | | Just like commit f67676d160c6 for read/write requests, this one ensures that the sockaddr data has been copied for IORING_OP_CONNECT if we need to punt the request to async context. Signed-off-by: Jens Axboe <axboe@kernel.dk>
* io_uring: ensure async punted sendmsg/recvmsg requests copy dataJens Axboe2019-12-033-64/+156
| | | | | | | | Just like commit f67676d160c6 for read/write requests, this one ensures that the msghdr data is fully copied if we need to punt a recvmsg or sendmsg system call to async context. Signed-off-by: Jens Axboe <axboe@kernel.dk>
* io_uring: ensure async punted read/write requests copy iovecJens Axboe2019-12-021-62/+181
| | | | | | | | | | | | | | Currently we don't copy the iovecs when we punt to async context. This can be problematic for applications that store the iovec on the stack, as they often assume that it's safe to let the iovec go out of scope as soon as IO submission has been called. This isn't always safe, as we will re-copy the iovec once we're in async context. Make this 100% safe by copying the iovec just once. With this change, applications may safely store the iovec on the stack for all cases. Reported-by: 李通洲 <carter.li@eoitek.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
* io_uring: add general async offload contextJens Axboe2019-12-021-24/+32
| | | | | | | | | | | | Right now we just copy the sqe for async offload, but we want to store more context across an async punt. In preparation for doing so, put the sqe copy inside a structure that we can expand. With this pointer added, we can get rid of REQ_F_FREE_SQE, as that is now indicated by whether req->io is NULL or not. No functional changes in this patch. Signed-off-by: Jens Axboe <axboe@kernel.dk>
* block: don't send uevent for empty disk when not invalidatingEric Biggers2019-12-021-1/+1
| | | | | | | | | | | | | | | | Commit 6917d0689993 ("block: merge invalidate_partitions into rescan_partitions") caused a regression where systemd-udevd spins forever using max CPU starting at boot time. It's caused by a behavior change where a KOBJ_CHANGE uevent is now sent in a case where previously it wasn't. Restore the old behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's switch the driver to using threaded IRQ so that we do not need to manage the interrupt and work separately, and we do not acknowledge interrupt until we finished handling it completely.

This controller is similar to the ILI210x and ILI251x, except for the following differences: - Reading out of touch data must happen at most 300 mS after the interrupt line was asserted. No command must be sent, the data are returned upon pure I2C read of 43 bytes long. - Supports 10 simultaneous touch inputs. - Touch data format is slightly different.
