Hi, This patch set fixes message continuation breakage involved with structured printk. A SCSI driver may output two continuation error messages like scmd_printk("foo"); printf("bar\n"); Here, scmd_printk() is structured printk with key/value dictionary information. Structured printk became to forcibly start a new line from commit c313af14, so those SCSI continuation error messages are divided as follows: [1234.567890] sd 2:0:0:0: [sdb] foo [1234.567893] bar <---- Divided However, the SCSI driver may expect following continuation error messages: [1234.567893] sd 2:0:0:0: [sdb] foo bar When user tools handle the error messages, that divided message will create some inconveniences.
This patch set makes structured printk with dictionary information not start a new line. Moreover, when multiple structured printk messages are continued, this patch outputs those multiple dictionary information when we read /dev/kmsg.
