linux.git/io_uring/filetable.h, branch v6.0 Linux kernel source tree io_uring: let to set a range for file slot allocation 2022-07-25T00:39:16+00:00 Pavel Begunkov asml.silence@gmail.com 2022-06-25T10:55:38+00:00 6e73dffbb93cb8797cd4e42e98d837edf0f1a967 From recently io_uring provides an option to allocate a file index for operation registering fixed files. However, it's utterly unusable with mixed approaches when for a part of files the userspace knows better where to place it, as it may race and users don't have any sane way to pick a slot and hoping it will not be taken. Let the userspace to register a range of fixed file slots in which the auto-allocation happens. The use case is splittting the fixed table in two parts, where on of them is used for auto-allocation and another for slot-specified operations.

From recently io_uring provides an option to allocate a file index for
operation registering fixed files. However, it's utterly unusable with
mixed approaches when for a part of files the userspace knows better
where to place it, as it may race and users don't have any sane way to
pick a slot and hoping it will not be taken.

Let the userspace to register a range of fixed file slots in which the
auto-allocation happens. The use case is splittting the fixed table in
two parts, where on of them is used for auto-allocation and another for
slot-specified operations.

io_uring: split out fixed file installation and removal 2022-07-25T00:39:16+00:00 Jens Axboe axboe@kernel.dk 2022-06-13T10:42:56+00:00 f110ed8498afa6ff8e9a8c08fb26880e02117616 Put it with the filetable code, which is where it belongs. While doing so, have the helpers take a ctx rather than an io_kiocb. It doesn't make sense to use a request, as it's not an operation on the request itself. It applies to the ring itself.
