Hello Bart, This is when we have a subset of the paths fails.
As you know the remaining path wont be used until the eh_handler is either done
or is short circuited.
What I will do is set this up via my jammer and capture a test using latest
upstream.
Of course my customer pain points are all in

Hello Fred,
Your feedback is very useful, but please note that in my e-mail I used
the phrase "transport layer" to refer to the code in the Linux kernel in
which the fast_io_fail_tmo functionality has been implemented. The
following commit message from 10 years ago explains why the
fast_io_fail_tm
When sizeof is applied to a pointer typed expression, it gives
the size of the pointer. So, here do not use sizeof on pointer
type.
Problem found using Coccinelle.

Hello Folks,
We still suffer from periodic complaints in our large customer base regarding
the long recovery times for dm-multipath.
Most of the time this is when we have something like a switch back-plane issue
or an issue where RSCN'S are blocked coming back up the fabric.
Corner cases still b
There are multiple possible situations being intermixed in this discussion.
First, I assume you're talking only about random access devices (if you try
transport level error recover on a sequential access device - tape or SMR disk
- there are lots of additional complexities).

Chris Metcalf should be able to figure out whether we can just
