Some unused log levels have been removed, and kdump has used the different options to control the log levels for the first kernel and the second kernel. Therefore, let's update the kdump sysconfig accordingly. Signed-off-by: Lianbo Jiang <lijiang@redhat.com> Acked-by: Kairui Song <kasong@redhat.com>

# The kdump commandline is the command line that needs to be passed off to

# KDUMP_COMMANDLINE="ro root=LABEL=/"
|
|
# Dracut depends on proper root= options, so please make sure that appropriate
|
|
# root= options are copied from /proc/cmdline. In general it is best to append

# Logging is controlled by following variables in the first kernel:
|
|
# - @var KDUMP_STDLOGLVL - logging level to standard error (console output)

|
|
# - @var KDUMP_KMSGLOGLVL - logging level to /dev/kmsg (only for boot-time)
|
|
#
|
|
# In the second kernel, kdump will use the rd.kdumploglvl option to set the
|
|
# log level in the above KDUMP_COMMANDLINE_APPEND.
|
|
# - @var rd.kdumploglvl - logging level to syslog (by logger command)
