名称描述
do_blockdev_direct_IOThis is a library function for use by filesystem drivers
iomap_dio_rwmap_dio_rw() always completes O_[D]SYNC writes regardless of whether the IO* is being issued as AIO or not. This allows us to optimise pure data writes* to use REQ_FUA rather than requiring generic_write_sync() to issue a* REQ_FLUSH post write
