Hi Christophe,
We recently found a problem with mpathpersist using an allocation length
of > 8192 bytes for PERSISTENT RESERVE IN/OUT commands. This patch set
tries to fix it. The last patch would change the ABI for external programs,
it's optional.
(Christophe, to avoid misunderstanding: This set is not meant to be included
in the upcoming merge).
Reviews and comments welcome.
Regards,
Martin
