Similar with SIOCOUTQ ioctl, the information is transport-dependent. The first patch adds SIOCINQ ioctl support in AF_VSOCK. Thanks to @dexuan, the second patch is to fix the issue where hyper-v `hvs_stream_has_data()` doesn't return the readable bytes. The third patch wraps the ioctl into `ioctl_int()`, which implements a retry mechanism to prevent immediate failure. The last one adds two test cases to check the functionality. The changes have been tested, and the results are as expected. ==================== Link: https://patch.msgid.link/20250708-siocinq-v6-0-3775f9a9e359@antgroup.com Signed-off-by: Jakub Kicinski --- 3b932976e0a1372ceaba0ceddec27e07d49e5715
