[PATCH] null dereference in fs/jbd2/journal.c
This is Eric Sesterhenn's jbd patch applied to jbd2.
Commit: 41716c7c21b15e7ecf14f0caf1eef3980707fb74
His words:
Since commit d1807793e1e7e502e3dc047115e9dbc3b50e4534 we dereference a NULL
pointer. Coverity id #1432. We set journal to NULL, and use it directly
afterwards.
