Hi,

I am fuzzing the kernel 4.13-rc7 with Syzkaller with Reiserfs. I am
getting the following crash:

INFO: task kworker/0:3:1103 blocked for more than 120 seconds.


Here is the full stack trace. I noticed that there are a few tasks
holding a sbi->lock. Below are a report and a log of all the programs
executing at the time of the incident.

I don't have a reproducer yet and any assistance would be appreciated.
