Merge tag 'io_uring-6.16-20250630' of git://git.kernel.dk/linux
Pull io_uring fix from Jens Axboe:
"Now that anonymous inodes set S_IFREG, this breaks the io_uring
read/write retries for short reads/writes. As things like timerfd and
eventfd are anon inodes, applications that previously did:
unsigned long event_data[2];
io_uring_prep_read(sqe, evfd, event_data, sizeof(event_data), 0);
and just got a short read when 1 event was posted, will now wait for
the full amount before posting a completion.
This caused issues for the ghostty application, making it basically
unusable due to excessive buffering"
