From fcce8a44dfa39bbcf1e7c9fccf87273edc7c5d32 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Fri, 22 May 2026 11:02:46 +0200 Subject: [PATCH] btrfs: zoned: don't account data relocation space-info in statfs free space [ Upstream commit 52416a27aabc43eab3792fd0ca9f5dabeab58f31 ] Don't account the free space in a data relocation space-info sub-group as usable free space in statfs. This is misleading as no user allocations can be made in this space-info sub-group. It is only a target for relocation.
