Ok, on 32-bit x86 without CONFIG_LBD I can reliably reproduce the issue with the following script:
#!/bin/bash
TESTDIR=/mnt/test SCRATCHMNT=/mnt/scratch file=$SCRATCHMNT/f
do_pwrite() { offset=`expr $1 \* 512` end=`expr $2 \* 512` length=`expr $end - $offset`
xfs_io -d -f $file -c "pwrite $offset $length" >/dev/null }
mkfs.xfs \ -b size=1024 \ -d file,name=$TESTDIR/fsfile,size=40146592b,agcount=16 \ -i attr=0 \ -l version=1
mount -o loop,rw,noatime,nodiratime $TESTDIR/fsfile $SCRATCHMNT
