Hi Jason,

This patch series fixes a deadlock in the ib_srp driver that was discovered
by syzbot. Please consider these patches for kernel v5.18.

Thanks,

Bart.

Changes compared to v1:
- Dropped patch 2/3, the patch that converts a spinlock into a mutex.
- Simplified patch 3/3 by removing a flush_work() loop.
