If a '$PERF_BUILDID_DIR'(typically $HOME/.debug) is a symbolic link directory, cutting of the path will fail. Here is an example where a buildid directory is a symbolic link. / # ls -al /root lrwxrwxrwx 1 root root 13 Mar 26 2012 /root -> opt/home/root / # cd ~ /opt/home/root # perf record -a -g sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.322 MB perf.data (~14057 samples) ] /opt/home/root # perf archive tar: Removing leading `/' from member names Now please run: $ tar xvf perf.data.tar.bz2 -C ~/.debug wherever you need to run 'perf report' on. /opt/home/root # mkdir temp /opt/home/root # tar xf perf.data.tar.bz2 -C ./temp /opt/home/root # find ./temp -name "*kernel*" ./temp/opt/home/root/.debug/[kernel.kallsyms] -> If successfully cut off the path, [kernel.kallsyms] is located in top of the archived file.

GCC's NULL is actually __null, which allows detecting some questionable NULL usage and warn about it. Moreover each platform/compiler should have its own stddef.h anyway (which is different from linux/stddef.h). So there's no good reason to leak kernel's NULL to userspace and override what the compiler provides.

After a few hectic block IO core changes for 3.3 and 3.2, I'm quite happy with a slow round. Really minor stuff in here, the only real functional change is making the auto-unplug threshold a per-queue entity. The threshold is set so that it's low enough that we don't hold off IO for too long, but still big enough to get a nice benefit from the batched insert (and hence queue lock cost reduction).

The OMAP driver needs a 'depends on ARCH_OMAP2PLUS' since it only builds for OMAP2+ platforms. This 'depends on' was in the original patch from Russell King, but was erroneously removed by me when making this option user-selectable in commit b09db45c (cpufreq: OMAP driver depends CPUfreq tables.) This patch remedies that. Apologies to Russell King for breaking his originally working patch. Also, thanks to Grazvydas Ignotas for reporting the same problem.

The invocation of softirq is now handled by irq_exit(), so there is no need for sparc64 to invoke it on the trap-return path. In fact, doing so is a bug because if the trap occurred in the idle loop, this invocation can result in lockdep-RCU failures. The problem is that RCU ignores idle CPUs, and the sparc64 trap-return path to the softirq handlers fails to tell RCU that the CPU must be considered non-idle while those handlers are executing. This means that RCU is ignoring any RCU read-side critical sections in those handlers, which in turn means that RCU-protected data can be yanked out from under those read-side critical sections. The shiny new lockdep-RCU ability to detect RCU read-side critical sections that RCU is ignoring located this problem. The fix is straightforward: Make sparc64 stop manually invoking the softirq handlers. Reported-by: Meelis Roos <mroos@linux.ee> Suggested-by: David Miller <davem@davemloft.net> Signed-off-by: Paul E.

This reverts commit 953742c8. Dumping two lines into autoconf.h for all existing Kconfig options results in a giant file (~16k lines) we have to process each time we compile something.

Paul Gortmaker authored
Using IS_ENABLED() within C (vs. within CPP #if statements) in its current form requires us to actually define every possible bool/tristate Kconfig option twice (__enabled_* and __enabled_*_MODULE variants). This results in a huge autoconf.h file, on the order of 16k lines for a x86_64 defconfig. Fixing IS_ENABLED to be able to work on the smaller subset of just things that we really have defined is step one to fixing this. Which means it has to not choke when fed non-enabled options, such as: include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef] The original prototype of how to implement a C and preprocessor compatible way of doing this came from the Google+ user "comex ." in response to Linus' crowdsourcing challenge for a possible improvement on his earlier C specific solution: #define config_enabled(x) (__stringify(x)[0] == '1') In this implementation, I've chosen variable names that hopefully make how it works more understandable.

A user reported that booting his box up with btrfs root on 3.4 was way slower than on 3.3 because I removed the ideal caching code. It turns out that we don't load the free space cache if we're in a commit for deadlock reasons, but since we're reading the cache and it hasn't changed yet we are safe reading the inode and free space item from the commit root, so do that and remove all of the deadlock checks so we don't unnecessarily skip loading the free space cache. The user reported this fixed the slowness.

sizeof(void*) returns an unsigned long, but it was being used as a width parameter to a "%-*s" format string which requires an int. On 64 bit platforms this causes a type mismatch: linux/kernel/irq/irqdomain.c:575: warning: field width should have type 'int', but argument 6 has type 'long unsigned int' This change casts the size to an int so printf gets the right data type.

If, in __persistent_ram_init(), the call to persistent_ram_buffer_init() fails or the call to persistent_ram_init_ecc() fails then we fail to free the memory we allocated to 'prz' with kzalloc() - thus leaking it. To prevent the leaks I consolidated all error exits from the function at a 'err:' label at the end and made all error cases jump to that label where we can then make sure we always free 'prz'. This is safe since all the situations where the code bails out happen before 'prz' has been stored anywhere and although we'll do a redundant kfree(NULL) call in the case of kzalloc() itself failing that's OK since kfree() deals gracefully with NULL pointers and I felt it was more important to keep all error exits at a single location than to avoid that one harmless/redundant kfree() on a error path.
