From adcf4ee64291b701d083bacf653eb10a4c46acd7 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 4 Dec 2023 00:38:56 -0500 Subject: bcachefs: Convert compression_stats to for_each_btree_key2 for_each_btree_key2() runs each loop iteration in a btree transaction, and thus does not cause SRCU lock hold time problems.
