[PATCH v2 2/2] x86: kexec_file: print appropriate variable
From: Åukasz Stelmach
Date: Thu Apr 30 2020 - 12:32:24 EST
The value of kbuf->memsz may be different than kbuf->bufsz after calling
kexec_add_buffer(). Hence both values should be logged.
Fixes: ec2b9bfaac44e ("kexec_file: Change kexec_add_buffer to take kexec_buf as argument.")
Fixes: 27f48d3e633be ("kexec-bzImage64: support for loading bzImage using 64bit entry")
Fixes: dd5f726076cc7 ("kexec: support for kexec on panic using new system call")
