From 2ef9d73f2b3b7f9c9c36c2a5bab5f44381867c16 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Sat, 15 Feb 2025 16:28:06 +1030 Subject: [PATCH] btrfs: remove the subpage related warning message Since the initial enablement of block size < page size support for btrfs in v5.15, we have hit several milestones for block size < page size (subpage) support: - RAID56 subpage support In v5.19 - Refactored scrub support to support subpage better In v6.4 - Block perfect (previously requires page aligned ranges) compressed write In v6.13 - Various error handling fixes involving subpage In v6.14 Finally the only missing feature is the pretty simple and harmless inlined data extent creation, just added in previous patches. Now btrfs has all of its features ready for both regular and subpage cases, there is no reason to output a warning about the experimental subpage support, and we can finally remove it now.
