* 2.4.13 errors and warnings @ 2001-10-28 9:58 Keith Owens 2001-10-28 18:03 ` Greg KH 0 siblings, 1 reply; 8+ messages in thread From: Keith Owens @ 2001-10-28 9:58 UTC (permalink / raw) To: linux-kernel Doing kbuild 2.5 full build for SMP on 2.4.13 got lots of warnings and a couple of errors. The .config had everything built in except for: # I don't have the required input files to build the sound firmware. # If anybody has them and can test, go for it. CONFIG_PSS_HAVE_BOOT=n CONFIG_MAUI_HAVE_BOOT=n CONFIG_TRIX_HAVE_BOOT=n # _SOUND_MSNDCLAS=y and _SOUND_MSNDPIN=y insist on having firmware that # I don't have. CONFIG_SOUND_MSNDCLAS=m CONFIG_SOUND_MSNDPIN=m # Broken code, missing ioctls CONFIG_SCSI_CPQFCTS=n # Broken code, missing #include <module.h> CONFIG_SCSI_U14_34F=n # Broken code, SCSI_ABORT_PENDING undefined CONFIG_USB_HPUSBSCSI=n The last three options give compile errors when they are turned on. I have not checked if they are fixed in 2.4.14-pre3.

Saves me having to send another patch later. If everybody did this Linus would get 1001 unnecessary changes for 1002 patches... Look, this isn't 2.5. Everyone else has to separate out their 2.5 patches. You're not special, you need to do it too... Let's actually take another half-second when sending patches to make sure Linus only gets the changes destined for 2.4. Keep the patch noise down, and help out not only Linus but everyone else reviewing 2.4 code.

A couple of months ago I thought about this and could think of two possible solutions: o add a __moddevtable which expands to __devinitdata __attribute((unused)). Drawback: Needs changing of all drivers which produce the warning. o add a variable which references the table within MODULE_DEVICE_TABLE. I implemented this, minor drawback is that it costs 4 bytes per table. However, IIRC Keith didn't like it at this time. The best option, of course, is to move drivers to the new-style pci or whatever interface, such that the table actually gets used. But the middle of a stable series is not necessarily the best time to do so. --Kai ^ permalink raw reply [flat|nested] 8+ messages in thread

The MODULE_DEVICE_TABLE referenced structure is only needed if the drivers are compiled as modules. The code uses a different usb_device_id structure to register itself with the usb-serial core (see the code for the reason why.) Keith's proposed change looks like it will solve this problem nicely. thanks, greg k-h ^ permalink raw reply [flat|nested] 8+ messages in thread
