[bug report] blktests srp/002 hang

[Shinichiro Kawasaki <shinichiro.kawasaki@xxxxxxx>]

I observed a process hang at the blktests test case srp/002 occasionally, using
kernel v6.5-rcX. Kernel reported stall of many kworkers [1]. PID 2757 hanged at
inode_sleep_on_writeback(). Other kworkers hanged at __inode_wait_for_writeback.

The hang is recreated in stable manner by repeating the test case srp/002 (from
15 times to 30 times).

I bisected and found the commit 9b4b7c1f9f54 ("RDMA/rxe: Add workqueue support
for rxe tasks") looks like the trigger commit. When I revert it from the kernel
v6.5-rc7, the hang symptom disappears. I'm not sure how the commit relates to
the hang. Comments will be welcomed.
