Name:Set an error in the dio if none is set yet. We have to use cmpxchg* as the submission context and the completion context(s) can race to* update the error.
Proto:static inline void iomap_dio_set_error(struct iomap_dio *dio, int ret)
Type:void
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct iomap_dio * | dio | |
| int | ret |
| Name | Describe |
|---|---|
| iomap_dio_bio_end_io | |
| iomap_dio_rw | map_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 |
