2013-10-09target: Fix assignment of LUN in tracepointsRoland Dreier
The unpacked_lun field in the SCSI target tracepoints should be initialized with cmd->orig_fe_lun rather than cmd->se_lun->unpacked_lun for two reasons: - most importantly, if we are in the cmd_complete tracepoint returning a check condition due to no LUN found, cmd->se_lun will be NULL and we'll crash trying to dereference it. - also, in any case, cmd->se_lun->unpacked_lun is an internal index into the target's internal set of LUNs; cmd->orig_fe_lun is much more useful and interesting, since it's the value the initiator actually sent.

2013-10-09target: Make target_do_xcopy failures return INVALID_PARAMETER_LISTNicholas Bellinger
This patch changes target_do_xcopy() to properly return TCM_INVALID_PARAMETER_LIST instead of TCM_INVALID_CDB_FIELD for failures related to the EXTENDED_COPY parameter list parsing. Also, move struct xcopy_op allocation ahead of kmapping to handle the special TCM_OUT_OF_RESOURCES case.

2013-10-09tools/perf/build: Pass through LDFLAGS to feature testsIngo Molnar
David Ahern reported that when passing in LDFLAGS=-static then the feature checks still succeed - causing build failures down the line because the static libraries are missing.

2013-10-09tools/perf/build: Fix O=/some/dir perf.o type of targetsIngo Molnar
If someone specifies a single target, mixed with O=, the following way: hubble:~/tip/tools/perf> make O=/tmp/perf util/stat.o BUILD: Doing 'make -j8' parallel build gcc -Wbad-function-cast -Wdeclaration-after-statement -Wformat-security -Wformat-y2k [...] The build might even fail, if a target depends on other targets: hubble:~/tip/tools/perf> make O=/tmp/perf perf.o ... perf.c: In function ‘handle_options’: perf.c:155:21: error: ‘PERF_HTML_PATH’ undeclared (first use in this function) The correct way to invoke such targets is: hubble:~/tip/tools/perf> make O=/tmp/perf /tmp/perf/perf.o BUILD: Doing 'make -j8' parallel build GEN /tmp/perf/common-cmds.h CC /tmp/perf/perf.o But that's unnecessary typing and it's also easy to mistakenly build into the source directory. To fix this remove the generic suffix rules and add redirection to $(OUTPUT) for the most popular .o targets.

The detection of certain rarely detected features can be delayed to when they are actually needed.
