[Ocfs2-devel] About 2.6 porting bug 58 "system halt when unmount a volumeimmediately after read/write"

[Ling, Xiaofeng]

Yes, seems if umount only, it will print call trace:=20
"kernel BUG at /usr/src/linux-2.6.3/fs/buffer.c:2660!"
and the system is not halt,If then follows rmmod at once, there will be =
kernel panic and system halt.
So problem has ready happened when unmounting.
