Details

In the Linux kernel, the following vulnerability has been resolved: md/raid10: prevent soft lockup while flush writes Currently, there is no limit for raid1/raid10 plugged bio. While flushing writes, raid1 has condresched() while raid10 doesn't, and too many writes can cause soft lockup. Follow up soft lockup can be triggered easily with writeback test for raid10 with ramdisks: watchdog: BUG: soft lockup - CPU#10 stuck for 27s!

Note that unlimited plugged bio still need to be optimized, for example, in the case of lots of dirty pages writeback, this will take lots of memory and io will spend a long time in plug, hence io latency is bad.
