From 27df4f5045fc68766980c4dfba5ffc9ad1f71ebb Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Thu, 7 Feb 2019 10:45:47 -0800 Subject: [PATCH] xfs: split up allocation btree verifier Similar to the inode btree verifier, the same allocation btree verifier structure is shared between the by-bno (bnobt) and by-size (cntbt) btrees. This prevents the ability to distinguish magic values between them. Separate the verifier into two, one for each tree, and assign them appropriately. No functional changes.
