2011-04-28kbuild: implement several W= levelsSam Ravnborg2-29/+44
Building a kernel with "make W=1" produces far too much noise to be useful. Divide the warning options in three groups: W=1 - warnings that may be relevant and does not occur too often W=2 - warnings that occur quite often but may still be relevant W=3 - the more obscure warnings, can most likely be ignored When building the whole kernel, those levels produce: W=1 - 4859 warnings W=2 - 1394 warnings W=3 - 86666 warnings respectively. Warnings have been counted with Geert's script at http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/linux-log-summary.pl Many warnings occur from .h files so fixing one file may have a nice effect on the total number of warnings. With these changes I am actually tempted to try W=1 now and then. Previously there was just too much noise. Borislav: - make the W= levels exclusive - move very noisy and making little sense for the kernel warnings to W=3 - drop -Woverlength-strings due to useless warning message - copy explanatory text for the different warning levels to 'make help' - recount warnings per level Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Borislav Petkov <bp@alien8.de> Cc: Dave Jones <davej@redhat.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Michal Marek <mmarek@suse.cz>

2011-04-18initramfs: Use KBUILD_BUILD_TIMESTAMP for generated entriesMichal Marek3-15/+50
gen_init_cpio gets the current time and uses it for each symlink, special file, and directory. Grab the current time once and make it possible to override it with the KBUILD_BUILD_TIMESTAMP variable for reproducible builds. Signed-off-by: Michal Marek <mmarek@suse.cz>
2011-04-18kbuild: Allow to override LINUX_COMPILE_BY and LINUX_COMPILE_HOST macrosMichal Marek2-2/+24
Make it possible to override the user@host string displayed during boot and in /proc/version by the environment variables KBUILD_BUILD_USER and KBUILD_BUILD_HOST. Several distributions patch scripts/mkcompile_h to achieve this, so let's provide an official way. Also, document the KBUILD_BUILD_TIMESTAMP variable while at it.

2011-04-15kbuild: move KALLSYMS_EXTRA_PASS from Kconfig to MakefileArtem Bityutskiy2-17/+8
At the moment we have the CONFIG_KALLSYMS_EXTRA_PASS Kconfig switch, which users can enable or disable while configuring the kernel. This option is then used by 'make' to determine whether an extra kallsyms pass is needed or not. However, this approach is not nice and confusing, and this patch moves CONFIG_KALLSYMS_EXTRA_PASS from Kconfig to Makefile instead. The rationale is below. 1. CONFIG_KALLSYMS_EXTRA_PASS is really about the build time, not run-time. There is no real need for it to be in Kconfig. It is just an additional work-around which should be used only in rare cases, when someone breaks kallsyms, so Kbuild/Makefile is much better place for this option. 2. Grepping CONFIG_KALLSYMS_EXTRA_PASS shows that many defconfigs have it enabled, probably not because they try to work-around a kallsyms bug, but just because the Kconfig help text is confusing and does not really make it clear that this option should not be used unless except when kallsyms is broken. 3. And since many people have CONFIG_KALLSYMS_EXTRA_PASS enabled in their Kconfig, we do might fail to notice kallsyms bugs in time. E.g., many testers use "make allyesconfig" to test builds, which will enable CONFIG_KALLSYMS_EXTRA_PASS and kallsyms breakage will not be noticed. To address that, this patch: 1. Kills CONFIG_KALLSYMS_EXTRA_PASS 2. Changes Makefile so that people can use "make KALLSYMS_EXTRA_PASS=1" to enable the extra pass if needed. Additionally, they may define KALLSYMS_EXTRA_PASS as an environment variable. 3. By default KALLSYMS_EXTRA_PASS is disabled and if kallsyms has issues, "make" should print a warning and suggest using KALLSYMS_EXTRA_PASS Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> [mmarek: Removed make help text, is not necessary] Signed-off-by: Michal Marek <mmarek@suse.cz>
2011-04-15Kconfig: improve KALLSYMS_ALL documentationArtem Bityutskiy1-6/+12
Dumb users like myself are not able to grasp from the existing KALLSYMS_ALL documentation that this option is not what they need. Improve the help message and make it clearer that KALLSYMS is enough in the majority of use cases, and KALLSYMS_ALL should really be used very rarely.

2011-03-29fs: don't use igrab() while holding i_lockDave Chinner3-4/+5
Fix the incorrect use of igrab() inside the i_lock in NFS and Ceph‥ If we are already holding the i_lock, we have a reference to the inode so we can safely use ihold() to gain an extra reference. This avoids hangs due to lock recursion on the i_lock now that the inode_lock is gone and igrab() uses the i_lock itself.
