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.
