From f4585e82340bfd351339104cc3a03e2f7d4c2e9d Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 16 Sep 2021 12:21:56 -0700 Subject: xfs: stricter btree height checking when looking for errors Since each btree type has its own precomputed maxlevels variable now, use them instead of the generic XFS_BTREE_MAXLEVELS to check the level of each per-AG btree.
