如何将软件的commit制作成patch并打入到源代码中，此处以glibc为例
下载源码
git clone https://github.com/bminor/glibc.git
切到出问题的分支
git checkout openEuler-22.03-LTS-SP4_update20240819
git log --oneline --graph
找在这个分支上提交的commit
[root@host-192-168-0-169 glibc]# git log --oneline openEuler-22.03-LTS-SP4-release..openEuler-22.03-LTS-SP4_update20240819 --graph

* adfa6cb !850 [PATCH] Check the validity of len before mmap
* 427e426 [PATCH] Check the validity of len before mmap
复制commit的hash值进行制作patch包
[root@host-192-168-0-169 glibc]# git format-patch 427e426..4a23394 #一个范围的提交制作成补丁
0001-stdlib-fix-grouping-verification-with-multi-byte-tho.patch
0002-fix-bug.patch
0003-mktime-improve-heuristic-for-ca-1986-Indiana-DST.patch
进入源代码路径，打入patch
# 检查patch能否正常应用
# 不应用修补程序,而是输出diffstat作为输入
git apply --stat xxx.patch
# 不应用修补程序,而是查看修补程序是否适用
git apply --check xxx.patch
# 应用补丁
patch -p1 < xxx.patch
# 也可以这样应用补丁
patch apply xxx.patch
