Re: [dm-devel] [PATCH v2] dm mpath: add feature flag to control call to blk_abort_queue

[Mike Anderson <andmike linux vnet ibm com>]

Mike S,

Thanks for doing the refresh / update of the patch.
I just did a quick test and did not see any issues but did have a couple
of questions.

Two questions:

1.) Should we bump the multipath targets version for this change?

2.) A general question on the length of the feature name
"abort_queue_on_failure" while the descriptive name is nice I noticed if
I have two features that the multipath output line starts wrapping. I
guess we could make the feature name shorter, but eventually if we added
more features the line would eventually wrap so a shorted name will just
stop wrapping now.

(I had a old experimental patch where I was trying to use the feature
flags to control the selection of fast fail flags to use and if full
recovery was done on the IO. The output was kinda messy, but that is to
be expected with this type of text interface vs a attribute based
alternative.)

Thanks,

-andmike
