  [PATCH v2 1/9] kexec_file: Remove unused members from struct kexec_buf. Thiago Jung Bauermann <bauerman@linux.vnet.ibm.com> - 2016-06-14 17:00 +0200

#1421983 — [PATCH v2 1/9] kexec_file: Remove unused members from struct kexec_buf.

kexec_add_buffer uses kexec_buf.buffer and kexec_buf.bufsz to pass along
its own arguments buffer and bufsz, but since they aren't used anywhere
else, it's pointless.
