KSMBD Adds SMB2 Compression Support In Linux 7.2

Merged back in Linux 5.15 in 2021 was KSMBD as an in-kernel SMB3 file server. There hasn't been much KSMBD news to report on recently but for Linux 7.2 there is now SMB2 compression support...

Why this matters
Why now

The continuous evolution of the Linux kernel drives ongoing improvements in networking and file sharing capabilities.

Why it’s important

Improved in-kernel SMB support enhances Linux's enterprise file serving capabilities, potentially increasing its adoption in mixed environments, particularly for high-performance computing and data centers.

What changes

Linux now offers more efficient file transfer for SMB2, reducing network bandwidth usage and improving performance for users accessing shared files.

Winners
  • · Linux systems administrators
  • · Enterprises using Linux file servers
  • · Open-source software community
Losers
  • · Proprietary file server solutions that compete on performance
Second-order effects
Direct

Enhanced KSMBD functionality in Linux 7.2 improves file sharing performance and efficiency for users.

Second

Increased adoption of Linux for primary file serving roles within organizations due to better performance and reduced overhead.

Third

Potential for an overall reduction in network traffic and associated energy consumption in data centers leveraging compressed SMB transfers.
