EROFS Metadata Compression Lands Plus A ~2.5x Speedup For Reading Directories
Merged on Monday were the EROFS file-system updates for Linux 6.17
As part of the merged EROFS code for Linux 6.17 is now supporting metadata compression for even smaller read-only file-system images. EROFS metadata compression is now in place for scoring even smaller image sizes but at the cost of higher I/O latency.
