Bart,
As reported by Pavel Tikhomirov it can happen that the SCSI error
handler does not get woken up. This is very annoying because it
results in a queue stall. The two patches in this series address this
issue without acquiring the SCSI host lock in the hot path. Please
consider these patches for kernel v4.16.
Applied to 4.16/scsi-queue. Thank you!
Is anyone finding a build error for this patch? I built allmodconfig on
Martin's 4.16/scsi-queue and I get this:
ERROR: "init_rcu_head" [drivers/scsi/scsi_mod.ko] undefined!
ERROR: "destroy_rcu_head" [drivers/scsi/scsi_mod.ko] undefined!
Reverting fixes it.
From a quick check, it seems the rcu funcitons are not exported, and
SCSI=m means hosts.c cannot reference it.
Cheers,
John
