Fixing KIO copy to USB stick and network filesystems
Summary
This KDE blog post explains a long-standing 15-year bug in KDE's KIO copy logic where copying to USB sticks and network filesystems completed before data was actually written. It outlines four KIO merge requests that implement a writeback window, using sync_file_range and fsync, to ensure accurate progress reporting and data integrity, with measurements across USB and SMB/NFS shares and notes on the KDE Frameworks 6.32 release.
