Hello Junjiro, after a long pause I'm trying newest aufs2-38, and I noticed a possible bug, here is how I reproduce it:
1) modprobe aufs 2) mount aufs with xino path on XFS filesystem (this will fail with error message in dmesg saying that xino on XFS is not supported) 3) the previous mount attempt will fail, but /sys/fs/aufs/si_eacf2c(etc) is created and remains accessible 4) rmmod aufs (this will not cleanup the file in /sys either) 5) ls /sys/fs/aufs/si_eacf2c(etc) ... this will cause some kernel paging request to fail in sysfs_readdir() I can send you full dmesg output but I think it's not needed IMHO aufs should cleanup the si_* entry in sysfs after the step 2 even if mounting fails due to xino on xfs.
