What it is

In the Linux kernel, the following vulnerability has been resolved:

ocfs2: cancel dqi_sync_work before freeing oinfo

ocfs2_global_read_info() will initialize and schedule dqi_sync_work at the

end, if error occurs after successfully reading global quota, it will

trigger the following warning with CONFIG_DEBUG_OBJECTS_* enabled:

ODEBUG: free active (active state 0) object: 00000000d8b0ce28 object type: timer_list hint: qsync_work_fn+0x0/0x16c

This reports that there is an active delayed work when freeing oinfo in

error handling, so cancel dqi_sync_work first. BTW, return status instead

of -1 when .read_file_info fails.
