This patch series avoids that SCSI error handling triggers an endless
loop and also restores reporting of QP errors in the kernel log.
Changes between v4 and v3:
- Added a patch that ensures that the SCSI host gets removed in time
when a user space process keeps queueing I/O during removal,
Remove an assignment that incorrectly overwrites the connection
state update by srp_connect_target().
