*	io_uring/fdinfo: fix sqe dumping for IORING_SETUP_SQE128	Jens Axboe	2022-09-21	1	-6/+26
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	If we have doubly sized SQEs, then we need to shift the sq index by 1 to account for using two entries for a single request. The CQE dumping gets this right, but the SQE one does not. Improve the SQE dumping in general, the information dumped is pretty sparse and doesn't even cover the whole basic part of the SQE. Include information on the extended part of the SQE, if doubly sized SQEs are in use. A typical dump now looks like the following: [...] SQEs: 32 32: opcode:URING_CMD, fd:0, flags:1, off:3225964160, addr:0x0, rw_flags:0x0, buf_index:0 user_data:2721, e0:0x0, e1:0xffffb8041000, e2:0x100000000000, e3:0x5500, e4:0x7, e5:0x0, e6:0x0, e7:0x0 33: opcode:URING_CMD, fd:0, flags:1, off:3225964160, addr:0x0, rw_flags:0x0, buf_index:0 user_data:2722, e0:0x0, e1:0xffffb8043000, e2:0x100000000000, e3:0x5508, e4:0x7, e5:0x0, e6:0x0, e7:0x0 34: opcode:URING_CMD, fd:0, flags:1, off:3225964160, addr:0x0, rw_flags:0x0, buf_index:0 user_data:2723, e0:0x0, e1:0xffffb8045000, e2:0x100000000000, e3:0x5510, e4:0x7, e5:0x0, e6:0x0, e7:0x0 [...] Fixes: ebdeb7c01d02 ("io_uring: add support for 128-byte SQEs") Signed-off-by: Jens Axboe <axboe@kernel.dk>
*	io_uring/fdinfo: get rid of unnecessary is_cqe32 variable	Jens Axboe	2022-09-21	1	-10/+6
\| \| \| \| \| \| \| \| \|	We already have the cq_shift, just use that to tell if we have doubly sized CQEs or not. While in there, cleanup the CQE32 vs normal CQE size printing. Signed-off-by: Jens Axboe <axboe@kernel.dk>
*	io_uring: move a few private types to local headers	Jens Axboe	2022-07-24	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \|	Commit 3a3d47fa9cfd ("io_uring: make io_uring_types.h public") moved a bunch of io_uring types to a kernel wide header, so we could make tracing a bit saner rather than pass in a ton of arguments. However, there are a few types in there that are not really needed to be system wide. Move the cancel data and mapped buffers back to the appropriate io_uring local headers.

*	io_uring: kill extra io_uring_types.h includes	Pavel Begunkov	2022-07-24	1	-1/+0
\| \| \| \| \| \| \| \| \| \|	io_uring/io_uring.h already includes io_uring_types.h, no need to include it every time. Kill it in a bunch of places, it prepares us for following patches.

*	io_uring: introduce a struct for hash table	Pavel Begunkov	2022-07-24	1	-2/+2
\| \| \| \| \| \| \| \| \| \|	Instead of passing around a pointer to hash buckets, add a bit of type safety and wrap it into a structure.

*	io_uring: switch cancel_hash to use per entry spinlock	Hao Xu	2022-07-24	1	-3/+6
\| \| \| \| \| \| \| \| \| \| \| \|	Add a new io_hash_bucket structure so that each bucket in cancel_hash has separate spinlock. Use per entry lock for cancel_hash, this removes some completion lock invocation and remove contension between different cancel_hash entries.

*	io_uring: move fdinfo helpers to its own file	Jens Axboe	2022-07-24	1	-0/+191
	This also means moving a bit more of the fixed file handling to the filetable side, which makes sense separately too. Signed-off-by: Jens Axboe <axboe@kernel.dk>
