Subsystems with Object Lifetime Issues in Embedded Systems

Explore object lifetime issues in Linux subsystems, particularly in embedded systems, through this informative conference talk. Gain insights into the problems associated with managed device allocations and devm_kzalloc(), which can lead to unexpected kernel crashes and corruptions. Delve into an easy-to-understand introduction to the issue, followed by an in-depth investigation of affected subsystems, with a focus on those used in embedded systems. Examine potential solutions and their feasibility as presented by Wolfram Sang from Sang Engineering / Renesas. Learn how this topic has evolved from discussions at LinuxPlumbers 2022 and FOSDEM2023, and understand its implications for kernel development and stability in embedded environments.
