I am using v6.8-rc2 with xfsprogs 6.5.0 and xfstests v2024.01.14 (with your patch on top)

Using oracle OCI instance with 64k page size support.

config:

[default]
FSTYP=xfs
RESULT_BASE=$PWD/results/$HOST/$(uname -r)
DUMP_CORRUPT_FS=1
CANON_DEVS=yes
RECREATE_TEST_DEV=true
TEST_DEV=/dev/sdb2
TEST_DIR=/mnt/test
SCRATCH_DEV=/dev/sdb3
SCRATCH_MNT=/mnt/scratch
LOGWRITES_DEV=/dev/sdb4

[64k]
MKFS_OPTIONS='-f -m reflink=1,rmapbt=1, -i sparse=1, -b size=64k,'


If I use 600MB and if the tests run, then this is the xfs_info I am getting on
the test device (test device should have the same config as scratch as I use RECREATE_TEST_DEV=true):

[nix-shell:/mnt/linux/xfstests]$ sudo xfs_info /dev/sdb2
meta-data=/dev/sdb2              isize=512    agcount=4, agsize=102400 blks
         =                       sectsz=4096  attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=1, rmapbt=1
         =                       reflink=1    bigtime=1 inobtcount=1 nrext64=1
data     =                       bsize=65536  blocks=409600, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=65536  ascii-ci=0, ftype=1
log      =internal log           bsize=65536  blocks=2613, version=2
         =                       sectsz=4096  sunit=1 blks, lazy-count=1
realtime =none                   extsz=65536  blocks=0, rtextents=0

Let me know if you need more information.
