lib/glob.c provides a new glob_match() function, with arguments in (pattern, string) order. It replaced a private function with arguments in (string, pattern) order, but I didn't swap the call site... The result was the entire ATA blacklist was effectively disabled. Anyone have a brown paper bag to spare? The lesson for today is "I f***ed up *how* badly *how* many months ago?", er, I mean "RC Kernels Get Lousy Test Coverage". This was not a subtle break, but it made it through an entire RC cycle unreported, presumably because all the people doing testing have shiny bug-free hardware. (BTW, the original reason for the argument swap was to match fnmatch(3), as for a while implementing a full fnmatch() was being considered.)
