Technical description

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 cond_resched() 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! [md0_raid10:1293]
