buf_markdelayed
Mark a buffer as a delayed write: mark it dirty without actually scheduling I/O.
Declaration
void buf_markdelayed(buf_t bp);Parameters
- bp:
Buffer to mark.
Discussion
Data will be flushed to disk at some later time, not with brelse(). A sync()/fsync() or pressure necessitating reuse of the buffer will cause it to be written back to disk.
