From dd6867d45ecc3ca9bb5026ee5197a9d88f5d2888 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Wed, 4 Dec 2024 07:50:28 -0600 Subject: [PATCH 676/676] fs/xfs: fix large extent counters incompat feature support When large extent counter / NREXT64 support was added to grub, it missed a couple of direct reads of nextents which need to be changed to the new NREXT64-aware helper as well. Without this, we'll have mis-reads of some directories with this feature enabled. (The large extent counter fix likely raced on merge with 07318ee7e ("fs/xfs: Fix XFS directory extent parsing") which added the new direct nextents reads just prior, causing this issue.)
