Subject: [RFC PATCH 00/35] SCSI EH argument reshuffling
Date: Fri, 23 Jun 2017 15:02:20 +0200 [thread overview]
Message-ID: <1498222975-71858-1-git-send-email-hare@suse.de> (raw)
Hi all,
finally here's the patchset to revamp the SCSI EH callback arguments
which I promised to do (some years ago ...).
The overall idea is to match the scope of the eh_XXX callbacks with
the appropriate argument, eg eh_device_reset_handler() should have a
scsi device as argument etc.
Relying on the scsi command has the problem that
a) we're holding a reference on that command for the entire lifetime
of the error handling and
b) it leads to some 'interesting' driver implementations; some
higher-level EH callback implementations go through the list of
outstanding commands and try to abort this particular command only;
makes one wonder what'll happen to the other commands ...
However, this patchset has the nice side-effect that we don't need to
allocate an out-of-order scsi command in scsi_ioctl_reset(), but can
call the function directly. Which should make hch happy :-)
It's marked as an RFC as I'm not sure if everyone agrees with this
approach; hence speak up folks!
As usual, comments and reviews are welcome.
Hannes Reinecke (35):
