setlocalversion: use only the correct release tag for git-describe
Currently, setlocalversion uses any annotated tag for git-describe. If we are at a tagged commit, it will not append the commit hash. $ git checkout v6.2-rc1^ $ make -s defconfig kernelrelease 6.1.0-14595-g292a089d78d3 $ git tag -a foo -m foo $ make -s kernelrelease 6.1.0 If a local tag 'foo' exists, it pretends to be a released version '6.1.0', while there are many commits on top of it. The output should be consistent irrespective of such a local tag. Pass the correct release tag to --match option of git-describe. In the mainline kernel, the SUBLEVEL is always '0', which is omitted from the tag. KERNELVERSION annotated tag 6.1.0 -> v6.1 (mainline) 6.2.0-rc5 -> v6.2-rc5 (mainline, release candidate) 6.1.7 -> v6.1.7 (stable) To preserve the behavior in linux-next, use the tag derived from localversion* files if exists. In linux-next, the local version is specified by the localversion-next file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
