In particular, it indicates that registered buffers can be updated in-place, whereas before the full set would have to be unregistered first.

If an error happens processing the SQE, a +CQE with the appropriate error value will still be generated. Available since +kernel 5.17. +.TP +.B IORING_FEAT_LINKED_FILE +If this flag is set, then io_uring supports sane assignment of files for SQEs +that have dependencies. For example, if a chain of SQEs are submitted with +.B IOSQE_IO_LINK, +then kernels without this flag will prepare the file for each link upfront. +If a previous link opens a file with a known index, eg if direct descriptors +are used with open or accept, then file assignment needs to happen post +execution of that SQE. If this flag is set, then the kernel will defer +file assignment until execution of a given request is started. Available since +kernel 5.17. .PP The rest of the fields in the |
