Looks good. It also results in a slight reduction in code size:

   text    data     bss     dec     hex filename
 792234   99018     632  891884   d9bec fs/xfs/xfs.o.orig
 792090   99018     632  891740   d9b5c fs/xfs/xfs.o

Which means making it inline hasn't cost us anything at individual
call sites.
