[PATCH] EDAC: printk cleanup
This implements the following idea: On Monday 30 January 2006 19:22, Eric W. Biederman wrote: > One piece missing from this conversation is the issue that we need errors > in a uniform format. That is why edac_mc has helper functions. > > However there will always be errors that don't fit any particular model. > Could we add a edac_printk(dev, ); That is similar to dev_printk but > prints out an EDAC header and the device on which the error was found? > Letting the rest of the string be user specified. > > For actual control that interface may be to blunt, but at least for people > looking in the logs it allows all of the errors to be detected and > harvested.
