Not quite - stable/linux-6.12.y has no io_fixup_restart_res() at all.
What 6.12 does already have is the older inline ERESTART* -> -EINTR
switch inside io_rw_done(), which is the code ab05caca123c refactors
rather than the fix itself. The actual bug is still there: io_read()
ends with a bare "return ret;" after __io_read(), and io_read_mshot()'s
"ret <= 0" branch only does req_set_fail(), so an -ERESTARTSYS coming
out of __io_read() reaches userspace as -512 unconverted.
