Bob Peterson bdcb88562c [GFS2] soft lockup detected in databuf_lo_before_commit ... This is part 2 of the patch for bug #245832, part 1 of which is already in the git tree. The problem was that sdp->sd_log_num_databuf was not always being protected by the gfs2_log_lock spinlock, but the sd_log_le_databuf (which it is supposed to reflect) was protected. That meant there was a timing window during which gfs2_log_flush called databuf_lo_before_commit and the count didn't match what was really on the linked list in that window. So when it ran out of items on the linked list, it decremented total_dbuf from 0 to -1 and thus never left the "while(total_dbuf)" loop. The solution is to protect the variable sdp->sd_log_num_databuf so that the value will always match the contents of the linked list, and therefore the number will never go negative, and therefore, the loop will be exited properly.
