Hi, Hmm, contrary to ide-cd.c case there doesn't seem to be a need currently for moving code out of ide-floppy.c (and this patch series doesn't change that). Besides it would be better to just remove some structs like it has been done with i.e. struct atapi_capabilities_page in ide-cd.c case [1] because: * it is easier to audit/debug the code if you don't have to look at typedefs all the time just to see which bytes/bits the code is really accessing * not using typedefs will make the source code significantly smaller * documentation is publically available * these structs are not memory mapped [1] http://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg242747.html On Thursday 03 January 2008, Borislav Petkov wrote: > - do a white-space cleanup > - remove old crufty code untouched since at least 2005 Please try to not mix things like moving code around and doing actual changes because it makes patch review difficult (i.e. it took me quite a while to find "old crufty code" that has been removed)...
