printk: do not mangle valid userspace syslog prefixes
printk: do not mangle valid userspace syslog prefixes with /dev/kmsg
Log messages passed to the kernel log by using /dev/kmsg or /dev/ttyprintk
might contain a syslog prefix including the syslog facility value.
This makes printk to recognize these headers properly, extract the real log
level from it to use, and add the prefix as a proper prefix to the
log buffer, instead of wrongly printing it as the log message text.
Before:
$ echo '<14>text' > /dev/kmsg
$ dmesg -r
<4>[135159.594810] <14>text
After:
$ echo '<14>text' > /dev/kmsg
$ dmesg -r
<14>[ 50.750654] text
