hi all,

i'd like to create a new ioctl for use in my kernels [actually i already
have 8-)] but want to make sure that i follow any established procedure
for creating it before requesting it be included in the kernel.
 specifically, is there a way to ensure the ioctl number i use isn't in
use by anyone else? is there a central registry?

so far i've just picked an arbitrary number:

+#define KDGETKEYDOWNSTATE 0x4B80 /* read kernel keydown bit */

 #endif /* _LINUX_KD_H */

any tips, pointers appreciated.
