In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix crash when mount with quota enabled
There is a reported crash when mounting ocfs2 with quota enabled.
RIP: 0010:ocfs2_qinfo_lock_res_init+0x44/0x50 [ocfs2]

It is caused by when initializing dqi_gqlock, the corresponding dqi_type
and dqi_sb are not properly initialized.
This issue is introduced by commit 6c85c2c72819, which wants to avoid
accessing uninitialized variables in error cases. So make global quota
info properly initialized.
