Part of it is that the naming is a bit horrible. Maybe it should move to buffer.c and be called generic_buffer_fsync, or generic_block_fsync which still wouldn't be perfect but match the buffer.c naming scheme. > > > > +extern int __generic_file_fsync_nolock(struct file *, loff_t, loff_t, int); > > > > No need for the extern.
