From d03e3a9370c85cfc07cd5c816196dc66b888a536 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Sat, 15 Mar 2025 19:19:26 +1030 Subject: [PATCH] btrfs: move block perfect compression out of experimental features Commit 1d2fbb7f1f9e ("btrfs: allow compression even if the range is not page aligned") introduced the block perfect compression for block size < page size cases. Before that commit, if the fs block size is smaller than page size (aka subpage cases), compressed write is only enabled if the dirty range is fully page aligned. This block perfect compression support was introduced in v6.13, and has been tested for two kernel releases. I believe it's time to move it out of experimental features so that we can get more tests in the real world.
