Summary
In the Linux kernel, the following vulnerability has been resolved:
dm crypt: add cond_resched() to dmcrypt_write()
The loop in dmcrypt_write may be running for unbounded amount of time,
thus we need cond_resched() in it.
This commit fixes the following warning:
[ 3391.153255][ C12] watchdog: BUG: soft lockup - CPU#12 stuck for 23s! [dmcrypt_write/2:2897]
...
