From 3db15c6ca6feb2c5000a1cbb39c33866e0349abd Mon Sep 17 00:00:00 2001 From: David Sterba Date: Thu, 17 Apr 2025 11:17:01 +0200 Subject: [PATCH] btrfs: add debug build only WARN Add conditional WARN() wrapper that's enabled only in debug build. It should be used for unexpected conditions that should be noisy. Use it instead of ASSERT(0). As it will not lead to BUG() make sure that continuing is still possible, e.g. the error is handled anyway.
