kexec: use file name as the output message prefix (de90a6bc) · Commits · 戴 / test

kexec output message misses the prefix "kexec", when Dave Young split the kexec code. Now, we use file name as the output message prefix. Currently, the format of output message: [ 140.290795] SYSC_kexec_load: hello, world [ 140.291534] kexec: sanity_check_segment_list: hello, world Ideally, the format of output message: [ 30.791503] kexec: SYSC_kexec_load, Hello, world [ 79.182752] kexec_core: sanity_check_segment_list, Hello, world Remove the custom prefix "kexec" in output message.
