Name:Sync the bytes written if this was a synchronous write. Expect ki_pos* to already be updated for the write, and will return either the amount* of bytes passed in, or an error if syncing the file failed.
Proto:static inline ssize_t generic_write_sync(struct kiocb *iocb, ssize_t count)
Type:ssize_t
Parameter:
Type | Parameter | Name |
---|---|---|
struct kiocb * | iocb | |
ssize_t | count |
2855 | If ki_flags & IOCB_DSYNC Then |
2863 | Return count |
Name | Describe |

generic_file_write_iter | generic_file_write_iter - write data to a file*@iocb: IO state structure*@from: iov_iter with data to write* This is a wrapper around __generic_file_write_iter() to be used by most* filesystems. It takes care of syncing the file in case of O_SYNC file |
blkdev_write_iter | Write data to the block device. Only intended for the block device itself* and the raw driver which basically is a fake block device.* Does not take i_mutex for the write and thus is not for general purpose* use. |
dio_complete | dio_complete() - called when all DIO BIO I/O has been completed* This drops i_dio_count, lets interested parties know that a DIO operation* has completed, and calculates the resulting return code for the operation |
