Yes, that should not be an issue anymore. > > Do you really want to read every write that happens here for one > > specific offset? Why? > > No not particularly ;-) It was part of the above.

(I'm assuming you mean we > are using the wrong macros not that we shouldn't check) No, you probably shouldn't be checking most of these. If you really do need to check, then just do a simple "if()" check and handle it with "real" code that way. > I see some drivers with BUG, BUG_ON, BUILD_BUG, BUILD_BUG_ON_ZERO, > etc. No driver should ever add a BUG or BUG_ON as you never want to take a machine down for a reason you just detected. WARN or WARN_ON is fine though. And build issues are also ok, but I doubt you would ever need one in a driver. thanks, greg k-h _______________________________________________ devel mailing list [email protected] http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
