| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit c7b2eff059fcc2d1b7085ee3d84b79fd657a537b. Hugh Dickins explains: "It seems too little tested: "losetup -d /dev/loop0" fails with EINVAL because nothing sets lo_thread; but even when you patch loop_thread() to set lo->lo_thread = current, it can't survive more than a few dozen iterations of the loop below (with a tmpfs mounted on /tst): j=0 cp /dev/zero /tst while : do let j=j+1 echo "Doing pass $j" losetup /dev/loop0 /tst/zero mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1 mount -t ext2 /dev/loop0 /mnt umount /mnt losetup -d /dev/loop0 done it collapses with failed ioctl then BUG_ON(!bio). I think the original lo_done completion was more subtle and safe than the kthread conversion has allowed for." Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm using TAGS generated from "make TAGS" to read the kernel source code. When I met a ifdef block #ifdef CONFIG_FOO ... #endif in the soruce code I would like to know the meaning CONFIG_FOO to decide whether I should read inside the ifdef block or not. meaning CONFIG_FOO is well documented in Kconfig. So it is nice if I can jump to CONFIG_FOO entry in Kconfig from "#ifdef CONFIG_FOO" with the tag jump. Here is the patch to add symbols in Kconfig and defconfig to TAGS in "make TAGS" operation.

This allows to trace modversion changes back to what caused them. The dump format is the name of the type defined, followed by its definition (which is almost C): s#list_head struct list_head { s#list_head * next , * prev ; } The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef. The exported symbols do not define types, and thus do not have an x# prefix: nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 ) The symbol type defintion of a single file can be generated with: make fs/jbd/journal.symtypes If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that export symbols are generated. The single *.symtypes files can be combined into a single file after a kernel build with a script like the following: for f in $(find -name '*.symtypes' | sort); do f=${f#./} echo "/* ${f%.symtypes}.o */" cat $f echo done \ | sed -e '\:UNKNOWN:d' \ -e 's:[,;] }:}:g' \ -e 's:\([[({]\) :\1:g' \ -e 's: \([])},;]\):\1:g' \ -e 's: $::' \ $f \ | awk ' /^.#/ { if (defined[$1] == $0) { print $1 next } defined[$1] = $0 } { print } ' When the kernel ABI changes, diffing individual *.symtype files, or the combined files, against each other will show which symbol changes caused the ABI changes.

| * kbuild: add option for stripping modules while installing themTheodore Ts'o2006-06-243-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add option for stripping modules while installing them. This function adds support for stripping modules while they are being installed. CONFIG_DEBUG_KERNEL (which will probably become more popular as developers use kdump) causes the size of the installed modules to grow by a factor of 9 or so. Some kernel package systems solve this problem by stripping the debug information from /lib/modules after running "make modules_install", but that may not work for people who are installing directly into /lib/modules --- root partitions that were sized to handle 16 megs worth of modules may not be quite so happy with 145 megs of modules, so the "make modules_install" never succeeds. This patch allows such users to request modules_install to strip the modules as they are installed. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

The reason is, that git name-rev --tags HEAD returns e.g. HEAD tags/v2.6.17-rc1^0~1067 which is currently good enough for setlocalversion to skip the suffix. This introduces a dependecy to grep -E, which should be fine.

| | | | | | | | | | | | | | | | | | | | | | kbuild does explicitly specify what to do in all cases, and each time make's built-in rules & variables has been used it has been a bug. So to speed up things and to avoid the hard-to-debug error situations ignore the built-in definitions. If any part of the kernel uses the built-in definitions the build will just stop there and it should be trivial to fix. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modules that uses GPL symbols can no longer be build with kbuild, the build will fail during the modpost step.

| | | | | | | | | | | | | | | | | | | | | | | | | | The binrpm-pkg target uses KERNELRELEASE when generated its .spec file. When binrpm-pkg was the first build target run in a tree it generated the .spec before kernel.release so the Version: tag in the .spec was empty. I don't know if this is the best fix, but binrpm-pkg works when we explicitly build kernel.release before descending into package-dir.

A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).
