Print log in init. c

First, the macro used to print logs in this file has error () Info () Notice (),These log macros are restricted in the system as follows:

# Define error (X...) log_write (3, "<3> init:" X)
# Define notice (X...) log_write (5, "<5> init:" X)
# Define Info (X...) log_write (6, "<6> init:" X)
# DefineLog_default_level3/* Messages <= this level are logged */

Log_default_level is 3, which is smaller than 3 and will be output to logcat. Therefore, when tracking logs in the file, the error can be printed out...

Next, useADB shell dmesg> kernel_log.log can be printed to the log of the kernel ~ This command is the kernel log command of the Qualcomm platform. May I ask the vendor from other platforms ~
