Reading /proc/filesystems Is Surprisingly Done Very Often & Now As Much As 444% Faster
Reading /proc/filesystems for obtaining a list of file-systems supported by the running kernel is done frequently on Linux. Namely due to being read by the SELinux library (libselinux), reading of /proc/filesystems is done more often than one would typically expect and now the Linux 7.2 kernel is optimizing for it to yield much better performance...
This optimization arrives as Linux continues its high-frequency usage in various system components, revealing previously unnoticed performance bottlenecks.
Improved kernel performance, even in seemingly minor areas, contributes to overall system efficiency, particularly for infrastructure and enterprise-level deployments where many such calls accumulate.
Linux systems, particularly those heavily relying on SELinux or frequent filesystem queries, will experience marginal but cumulative performance gains.

- · Cloud providers
- · SELinux users
- · Infrastructure software vendors
Linux 7.2 kernel will exhibit slightly improved general system responsiveness and resource utilization.
The cumulative effect across large-scale deployments could lead to minor reductions in operational costs related to compute resources.
This iterative optimization process highlights the continuous effort in foundational software to extract maximum efficiency, impacting future hardware requirements.
