    Subject[PATCH] aio: remove bare user-triggerable error printk
    Date
    aio: remove bare user-triggerable error printk

    The user can generate console output if they cause do_mmap() to fail during
    sys_io_setup(). This was seen in a regression test that does exactly that by
    spinning calling mmap() until it gets -ENOMEM before calling io_setup().

    We don't need this printk all, just remove it.
