IIRC Linux does not use typedefs much, so maybe typedefs combined with #defines confuse checkpatch.pl. But I don't know why this case would be different to: typedef long long int64_t; #define off_t int64_t void func(off_t *e); Perhaps using a typedef in place of #define could help but I'd not make such a change just to silence checkpatch. > > Regards, > Andreas > > -- > SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany > GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg
