[Ocfs2-devel] first mount error with latest code (revision 1086)

[Chen, Yukun]

Hi all
I encounter a "Segment Fault" when mount an ocfs2 partition. 
 
Steps to duplicate:
 
1.load_ocfs2
2.mkfs.ocfs2 -b 4 -L ocfs2 -F -m /ocfs /dev/sdc2
3.mount /dev/sdc2 /ocfs -t ocfs2
 
Then I get "Segment Fault" with following message produced by dmesg:
 
......
Unable to handle kernel NULL pointer dereference at virtual address
0000002c
 printing eip:

Any ideas for it?
