--- Comment #1 from Zorro Lang (zlang@redhat.com) ---
It's not 64k dir bsize related, just find another same panic on XFS with "-m
crc=1,finobt=1,reflink=1,rmapbt=1,bigtime=1,inobtcount=1 -b size=1024". Hmmm...
"maybe rmapbt and -b size=1024 is related???". And other same condition is 2
panic jobs are all on aarch64 machine.
