[Ocfs2-devel] NULL pointer dereference in function ocfs2_abort_trigger

[Xue jiufei]

Hi all,
Function ocfs2_abort_trigger() use bh->b_assoc_map to get super block.
But I cannot find any function to set bh->b_assoc_map in ocfs2.
So it will trigger NULL pointer dereference while calling this
function.

I am wonder that whether function t_abort->ocfs2_abort_trigger() can be
deleted from ocfs2.

Thanks very much.

Better not, jdb2 aborted due to some error, let ocfs2 continue may cause
corruption.
