Smatch is a C static checker with a lot of kernel specific checks. You can download it from: http://repo.or.cz/w/smatch.git. Or if you prefer a github mirror, then you can download it from https://github.com/error27/smatch It's a simple process to run Smatch on a file in the kernel: yum install gcc make sqlite3 sqlite-devel sqlite perl-DBD-SQLite openssl-devel perl-Try-Tiny make cd ~/path/to/kernel_dir ~/smatch_dir/smatch_scripts/kchecker drivers/whatever/file.c Overall, this release is mostly small fixes all over. The main improvement is better tracking changes to container_of(). For example, there are a lot of kernel release functions which free the container_of(). The next step is to figure out the correct free function to call for put_device(). Special thanks to Elena Reshetova who wrote a new module to track host/VMM data for confidential computing. And also to thanks to Christophe JAILLET for a bunch of fixes and updates. Please test and let me know if you find any issues! regards, dan carpenter
