Originally EIOCBRETRY was used in fs/read_write.c for vector IO.
And EIOCBRETRY was deleted from it after.
Now EIOCBRETRY is used in driver

ely into sources we can see that
EIOCBQUEUED never may be returned to aio_run_iocb().

Could you point source line which "returns -EIOCBRETRY"?

Does it mean that EIOCBQUEUED is always reset and never returned?

If invalidate_inode_pages2_range() says it can not invalidate pages
It means that soft_irq does completing IO now on other cpu.
Next ret

EIOCBRETRY is used and caught already in do_sync_read() and
