2022-07-01scripts/tags.sh: Include tools directory in tags generationVipin Sharma1-8/+1
Add tools directory in generating tags and quiet the "No such file or directory" warnings. It reverts the changes introduced in commit 162343a876f1 ("scripts/tags.sh: exclude tools directory from tags generation") while maintainig the original intent of the patch to get rid of the warnings. This allows the root level cscope files to include tools source code besides kernel and a single place to browse the code for both.

2022-05-19scripts/tags.sh: Invoke 'realpath' via 'xargs'Cristian Ciocaltea1-4/+7
When COMPILED_SOURCE is set, running make ARCH=x86_64 COMPILED_SOURCE=1 cscope tags could throw the following errors: scripts/tags.sh: line 98: /usr/bin/realpath: Argument list too long cscope: no source files found scripts/tags.sh: line 98: /usr/bin/realpath: Argument list too long ctags: No files specified. Try "ctags --help". This is most likely to happen when the kernel is configured to build a large number of modules, which has the consequence of passing too many arguments when calling 'realpath' in 'all_compiled_sources()'. Let's improve this by invoking 'realpath' through 'xargs', which takes care of properly limiting the argument list.

2021-11-26scripts/tags: add space regexs to all regex_cZhaoyu Liu1-63/+63
When "make tags", it prompts a warning: ctags: Warning: drivers/pci/controller/pcie-apple.c:150: null expansion of name pattern "\1" The reason is that there is an indentation beside arguments of DECLARE_BITMAP, but it can parsed normally by gtags. It's also allowed in C. Regex [:space:] can match any white space character, so it's a better approach to add it to each item in regex_c.

2021-05-02kbuild: replace LANG=C with LC_ALL=CMasahiro Yamada1-1/+1
LANG gives a weak default to each LC_* in case it is not explicitly defined. LC_ALL, if set, overrides all other LC_* variables. LANG < LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, ... < LC_ALL This is why documentation such as [1] suggests to set LC_ALL in build scripts to get the deterministic result. LANG=C is not strong enough to override LC_* that may be set by end users.

2019-07-11kbuild: add a flag to force absolute path for srctreeMasahiro Yamada1-2/+1
In old days, Kbuild always used an absolute path for $(srctree). Since commit 890676c65d69 ("kbuild: Use relative path when building in the source tree"), $(srctree) is '.' when O= was not passed from the command line. Yet, using absolute paths is useful in some cases even without O=, for instance, to create a cscope file with absolute path tags. 'O=.' was known to work as a workaround to force Kbuild to use absolute paths even when you are building in the source tree. Since commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any directory"), Kbuild is too clever to be tricked. Even if you pass 'O=.' Kbuild notices you are building in the source tree, then use '.' for $(srctree). So, 'make O=. cscope' is no help to create absolute path tags. We cannot force one or the other according to commit e93bc1a0cab3 ("Revert "kbuild: specify absolute paths for cscope""). Both of relative path and absolute path have pros and cons. This commit adds a new flag KBUILD_ABS_SRCTREE to allow users to choose the absolute path for $(srctree). 'make KBUILD_ABS_SRCTREE=1 cscope' will work as a replacement of 'make O=. cscope'.

2019-05-03scripts/tags.sh: fix direct execution of scripts/tags.shMasahiro Yamada1-1/+1
I thought this script was run via "make tags" etc. but some people run it directly. Prior to commit a9a49c2ad9b9 ("kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build"), in such a usecase, "tree" was set empty since KBUILD_SRC is undefined. Now, "tree" is set to "${srctree}/", which is evaluated to "/". Fix it by taking into account the case where "srctree" is unset.

2019-04-02kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree buildMasahiro Yamada1-1/+1
KBUILD_SRC was conventionally used for some different purposes: [1] To remember the source tree path [2] As a flag to check if sub-make is already done [3] As a flag to check if Kbuild runs out of tree For [1], we do not need to remember it because the top Makefile can compute it by $(realpath $(dir $(lastword $(MAKEFILE_LIST)))) [2] has been replaced with self-commenting 'sub_make_done'. For [3], we can distinguish in-tree/out-of-tree by comparing $(srctree) and '.' This commit converts [3] to prepare for the KBUILD_SRC removal.

2018-06-07mm: split page_type out from _mapcountMatthew Wilcox1-3/+3
We're already using a union of many fields here, so stop abusing the _mapcount and make page_type its own field. That implies renaming some of the machinery that creates PageBuddy, PageBalloon and PageKmemcg; bring back the PG_buddy, PG_balloon and PG_kmemcg names. As suggested by Kirill, make page_type a bitmask. Because it starts out life as -1 (thanks to sharing the storage with _mapcount), setting a page flag means clearing the appropriate bit. This gives us space for probably twenty or so extra bits (depending how paranoid we want to be about _mapcount underflow).

2016-01-05tags: Unify emacs and exuberant rulesMichal Marek1-93/+109
The emacs rules were constantly lagging behind the exuberant ones. Use a single set of rules for both, to make the script easier to maintain. The language understood by both tools is basic regular expression with some limitations, which are documented in a comment. To be able to store the rules in an array and easily iterate over it, the script requires bash now. In the exuberant case, the change fixes some false matches in <linux/page-flags.h> and also some too greedy matches in the arguments of the DECLARE_*/DEFINE_* macros. In the emacs case, several previously not working rules are matching now.

2016-01-05tags: Treat header files as C codeMichal Marek1-33/+33
This allows to apply the same patters to both source and header files. The effect is mostly visible in the case of DECLARE_BITMAP, but there are small gains all over the place. There is also lots of random changes in the diff, I believe this is simply because there are still lots of unexpanded macros in the code and the C and C++ parsers fail and recover at different points. Also, qconf.h is parsed as C, but that's a negligible regression. Signed-off-by: Michal Marek <mmarek@suse.com>

2015-08-19scripts/tags.sh: Include trace_*_rcuidle() in tagsStephen Boyd1-0/+4
Every tracepoint creates two functions, the usual one 'trace_*()' and the rcuidle one 'trace_*_rcuidle()'. Add regex for the rcuidle variant so that we can jump to the tracepoints that use rcuidle.

2015-06-16init: delete the __cpuinit related stubsPaul Gortmaker1-1/+1
The __cpuinit support was removed several releases ago in 3.11-rc1 with commit 22f0a27367742f65130c0fb25ef00f7297e032c1 ("init.h: remove __cpuinit sections from the kernel") People have had a chance to update their out of tree code, so now we remove the no-op stubs to ensure no more new use cases can creep back in. Also delete the mention of __cpuinitdata from the tag script. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

This will simplify code when we add new flags. v3: - Kees pointed out that no_new_privs should never be cleared, so we shouldn't define task_clear_no_new_privs(). we define 3 macros instead of a single one. v2: - updated scripts/tags.sh, suggested by Peter Cc: Ingo Molnar <mingo@kernel.org> Cc: Miao Xie <miaox@cn.fujitsu.com> Cc: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: Zefan Li <lizefan@huawei.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2014-08-19scripts/tags.sh: fix DEFINE_HASHTABLE in emacs caseDirk Gouders1-1/+1
The emacs --regex for DEFINE_HASHTABLE produced a warning because of an unmatched '\('. Further, the whole entry did not work, because the regex needs to match from the beginning of a line, including keywords like 'static'. Finally, '\w' should not be used, because it stops at underscores which are often part of variable names in C, resulting in wrong entries in the tags file.
