I just tried patch #8872 and got the following compile error on ppc64:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>/root/lustre-release/build/BUILD/lustre-2.5.56/libcfs/libcfs/linux/linux-debug.c:188:28: error: asm/stacktrace.h: No such file or directory make[6]: *** [/root/lustre-release/build/BUILD/lustre-2.5.56/libcfs/libcfs/linux/linux-debug.o] Error 1 make[6]: *** Waiting for unfinished jobs.... </pre> </div></div> <p>This is because:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># pwd /root/kernel/rpmbuild/SOURCES/linux-2.6.32-431.5.1.el6/arch # find ./arm -name stacktrace.h ./arm/include/asm/stacktrace.h # find ./powerpc -name stacktrace.h # </pre> </div></div> <p>The stacktrace.h is supported by arm (although it does not support dump_trace), but not by powerpc.<br/> So, a check is still needed before "#include &lt;asm/stacktrace.h&gt;" in libcfs/libcfs/linux/linux-debug.c.</p> <p>Since we are only support dump_trace on X86 anyways this means we can move stacktrace.h and nmi.h to the CONFIG_X86 section of the patch.
