I think it'd be good if people would, when noticing defects in a specific subsystem, look for and correct the same defect treewide. IS_ERR already has an unlikely test so remove unnecessary unlikelys from the call sites. from: include/linux/err.h #define IS_ERR_VALUE(x) unlikely((x) >= (unsigned long)-MAX_ERRNO) [...] static inline long __must_check IS_ERR(const void *ptr) { return IS_ERR_VALUE((unsigned long)ptr); } Sending directly to maintainers for now, will resend in a month or so only to trivial if not picked up.
