Jens Axboe ba04291eb6 io_uring: allow use of offset == -1 to mean file position ... This behaves like preadv2/pwritev2 with offset == -1, it'll use (and update) the current file position. This obviously comes with the caveat that if the application has multiple read/writes in flight, then the end result will not be as expected. This is similar to threads sharing a file descriptor and doing IO using the current file position. Since this feature isn't easily detectable by doing a read or write, add a feature flags, IORING_FEAT_RW_CUR_POS, to allow applications to detect presence of this feature.
