Subject: [PATCH 1/6] log: change log level print in older kernels
|
|
|
|
In older kernels that have the variable-length-record log_buf, the
|
|
log level and the log flags/facility are not separated. Since the
|
|
log level is only the last three bits, and the flags/facility and
|
|
level are separated in 5.10 and later kernels, only print those last
|
|
three bits when using 'log -m'.
