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

28defbea · Zach Brown <[email protected]> · 2007-03-27 15:44:01 -07:00

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 at all, just remove it.
