2013-11-16Merge tag 'trace-3.13' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing update from Steven Rostedt: "This batch of changes is mostly clean ups and small bug fixes. The only real feature that was added this release is from Namhyung Kim, who introduced "set_graph_notrace" filter that lets you run the function graph tracer and not trace particular functions and their call chain. Tom Zanussi added some updates to the ftrace multibuffer tracing that made it more consistent with the top level tracing. One of the fixes for perf function tracing required an API change in RCU; the addition of "rcu_is_watching()". As Paul McKenney is pushing that change in this release too, he gave me a branch that included all the changes to get that working, and I pulled that into my tree in order to complete the perf function tracing fix" * tag 'trace-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Add rcu annotation for syscall trace descriptors tracing: Do not use signed enums with unsigned long long in fgragh output tracing: Remove unused function ftrace_off_permanent() tracing: Do not assign filp->private_data to freed memory tracing: Add helper function tracing_is_disabled() tracing: Open tracer when ftrace_dump_on_oops is used tracing: Add support for SOFT_DISABLE to syscall events tracing: Make register/unregister_ftrace_command __init tracing: Update event filters for multibuffer recordmcount.pl: Add support for __fentry__ ftrace: Have control op function callback only trace when RCU is watching rcu: Do not trace rcu_is_watching() functions ftrace/x86: skip over the breakpoint for ftrace caller trace/trace_stat: use rbtree postorder iteration helper instead of opencoding ftrace: Add set_graph_notrace filter ftrace: Narrow down the protected area of graph_lock ftrace: Introduce struct ftrace_graph_data ftrace: Get rid of ftrace_graph_filter_enabled tracing: Fix potential out-of-bounds in trace_get_user() tracing: Show more exact help information about snapshot

2013-11-13kernel-doc: improve "no structured comments found" errorJohannes Berg
When using '!Ffile function' in a docbook template, and the function no longer exists, you get a "no structured comments found" error from the kernel-doc processing script. It's useful to know which functions it was looking for, so print them out in this case. Also do the same for '!Pfile doc-section' The same error also happens when using '!Efile' when some exported functions aren't documented (in the same file.) There's a very large number of such functions though, so don't print the message in this case -- right now it would give ~850 messages.

2013-11-13initramfs: read CONFIG_RD_ variables for initramfs compressionP J P
When expert configuration option(CONFIG_EXPERT) is enabled, menuconfig offers a choice of compression algorithm to compress initial ramfs image; This choice is stored into CONFIG_RD_* variables. But usr/Makefile uses earlier INITRAMFS_COMPRESSION_* macros to build initial ramfs file. Since none of them is defined, resulting 'initramfs_data.cpio' file remains un-compressed. This patch updates the Makefile to use CONFIG_RD_* variables and adds support for LZ4 compression algorithm. Also updates the 'gen_initramfs_list.sh' script to check whether a selected compression command is accessible or not. And fall-back to default gzip(1) compression when it is not.

2013-11-13checkpatch: make the memory barrier test noisierJoe Perches
Peter Zijlstra prefers that comments be required near uses of memory barriers. Change the message level for memory barrier uses from a --strict test only to a normal WARN so it's always emitted. This might produce false positives around insertions of memory barriers when a comment is outside the patch context block.

Extend the CamelCase words found to include structure members. In https://lkml.org/lkml/2013/9/3/318 Sarah Sharp (mostly) wrote: "In general, if checkpatch.pl complains about a variable a patch introduces that's CamelCase, you should pay attention to it. Otherwise, [] ignore it." So, if checking a patch, scan the original patched file if it's available and add any preexisting CamelCase types so reuses do not generate CamelCase messages.

2013-09-23modpost: Optionally ignore secondary errors seen if a single module build failsGuenter Roeck
Commit ea4054a23 (modpost: handle huge numbers of modules) added support for building a large number of modules. Unfortunately, the commit changed the semantics of the makefile: Instead of passing only existing object files to modpost, make now passes all expected object files. If make was started with option -i, this results in a modpost error if a single file failed to build. Example with the current btrfs build falure on m68k: fs/btrfs/btrfs.o: No such file or directory make[1]: [__modpost] Error 1 (ignored) This error is followed by lots of errors such as: m68k-linux-gcc: error: arch/m68k/emu/nfcon.mod.c: No such file or directory m68k-linux-gcc: fatal error: no input files compilation terminated. make[1]: [arch/m68k/emu/nfcon.mod.o] Error 1 (ignored) This doesn't matter much for normal builds, but it is annoying for builds started with "make -i" due to the large number of secondary errors. Those errors unnececessarily clog any error log and make it difficult to find the real errors in the build. Fix the problem by adding a new parameter '-n' to modpost. If this parameter is specified, modpost reports but ignores missing object files. With this patch, error output from above problem is (with make -i): m68k-linux-ld: cannot find fs/btrfs/ioctl.o: No such file or directory make[2]: [fs/btrfs/btrfs.o] Error 1 (ignored) ... fs/btrfs/btrfs.o: No such file or directory (ignored) Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Michael Marek <mmarek@suse.cz> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

A sed command in scripts/config that used colons as separator was accidentally changed to use slashes, which fails when you use slashes in a value. Changing it back to colons is of course not a proper fix, but at least it will be broken in the same way it had been for four years. A proper fix is pending" * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: scripts/config: fix variable substitution command

2013-09-11checkpatch: add test for positional misuse of section specifiers like __initdataJoe Perches
As discussed recently on the arm [1] and lm-sensors [2] lists, it is possible to use section markers on variables in a way which gcc doesn't understand (or at least not the way the developer intended): static struct __initdata samsung_pll_clock exynos4_plls[nr_plls] = { does NOT put exynos4_plls in the .initdata section. The __initdata marker can be virtually anywhere on the line, EXCEPT right after "struct". The preferred location is before the "=" sign if there is one, or before the trailing ";" otherwise. [1] http://permalink.gmane.org/gmane.linux.ports.arm.kernel/258149 [2] http://lists.lm-sensors.org/pipermail/lm-sensors/2013-August/039836.html So, update checkpatch to find these misuses and report an error when it's immediately after struct or union, and a warning when it's otherwise not immediately before the ; or =.
