From 07b7f2e3172b97da2a7ac273ecbaf173cc09a9f4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 22 Feb 2024 12:35:21 -0800 Subject: xfs: move the btree stats offset into struct btree_ops The statistics offset is completely static, move it into the btree_ops structure instead of the cursor.
