Subject: [PATCH 3/3] 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.)
Fixes: aa7c1322671e ("fs/xfs: Add large extent counters incompat feature support")
