Is this comment from include/scsi/scsi_host.h still true?
/*
* This is an error handling strategy routine. You don't need to
* define one of these if you don't want to - there is a default
* routine that is present that should work in most cases. For those
* driver authors that have the inclination and ability to write their
* own strategy routine, this is where it is specified. Note - the
----> * strategy routine is *ALWAYS* run in the context of the kernel eh
----> * thread. Thus you are guaranteed to *NOT* be in an interrupt
----> * handler when you execute this, and you are also guaranteed to
----> * *NOT* have any other commands being queued while you are in the
* strategy routine. When you return from this function, operations
* return to normal.
*
* See scsi_error.c scsi_unjam_host for additional comments about
* what this function should and should not be attempting to do.
*
* Status: REQUIRED (at least one of them)
*/
Also what about this, about scsi_unjam_host() from scsi_error.c?
* Notes:
* When we come in here, we *know* that all commands on the bus have
* either completed, failed or timed out. we also know that no further
* commands are being sent to the host, so things are relatively quiet
* and we have freedom to fiddle with things as we wish.
I'm not seeing what code makes sure those are true.
Thanks,
