The Ultimate Guide To Lspatch Modules: Enhance Your Linux System

Author Linares 31 Jan 2025

The `lspatch` module in Python is a library that provides an interface to the `lspatch` system call, which is used to apply a patch to a running kernel. This can be useful for updating the kernel with security fixes or new features without having to reboot the system.

The `lspatch` module is relatively simple to use. To apply a patch, you simply need to call the `lspatch()` function and provide the path to the patch file. The `lspatch()` function will then apply the patch to the running kernel and return a status code. If the patch is applied successfully, the status code will be 0. Otherwise, the status code will be a non-zero value.

The `lspatch` module can be a valuable tool for system administrators who need to keep their kernels up to date. By using the `lspatch` module, system administrators can apply patches without having to reboot the system, which can save time and reduce the risk of downtime.
