before
# size fs/locks.o
text data bss dec hex filename
14712 48 4 14764 39ac fs/locks.o

after (with static inline)
# size fs/locks.o
text data bss dec hex filename
14648 48 4 14700 396c fs/locks.o


is "sooner or later" and "maybe someone else uses it" worth making
everyone elses kernel bigger by 500 bytes of code ?
