Hi, is there already a global function to reverse the bits in a byte?
If not, wouldn't it be useful to put an optimized function (e.g. with a 256-byte lookup-table, or 16-byte for the two nibbles to save space) into the kernel, or into libkern? Some drivers already implement their own reverse functions. And I ask, because I need one too, for a new I2C driver. -- Frank Wille
