[PATCH] target: tcmu: add missing pr attributes to passthrough backends

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In commit b49d6f7885306ee636d5c1af52170f3069ccf5f7 the new attribute
emulate_pr was added.
passthrough_parse_cdb() uses the attribute's value to distinguish,
whether reservation commands should be rejected or not.
But the new attribute was not added to passthrough_attrib_attrs, so in
pscsi and tcmu - the users of passthrough_parse_cdb() - the attribute
is not available to change parser's behavior.
This patch adds the new attribute as well as the "pr control" attributes
enforce_pr_isids and force_pr_aptpl to passthrough_attrib_attrs.
