I'd rather have a single helper for those checks, rather than open-coding IS_SYNC() + IOCB_DSYNC in each, for obvious reasons...
Yes, I think something like:
static inline bool iocb_is_sync(struct kiocb *iocb)
{
return (iocb->ki_flags & IOCB_DSYNC) ||
S_SYNC(iocb->ki_filp->f_mapping->host);
}
should do the job.
