Humble Chirammal 4a69378698 rbd: introduce a helper function to detect multi writer,block & rwofile ... SINGLE_NODE_WRITER capability ambiguity has been fixed in csi spec v1.5 which allows the SP drivers to declare more granular WRITE capability in form of SINGLE_NODE_SINGLE_WRITER or SINGLE_NODE_MULTI_WRITER. These are not really new capabilities rather capabilities introduced to get the desired functionality from CO side based on the capabilities SP driver support for various CSI operations, this new capabilities also help to address new access mode RWOP (readwriteoncepod). This commit adds a helper function which identity the request is of multiwriter mode and also validates whether it is filesystem mode or block mode. Based on the inspection it fails to allow multi write requests for filesystem mode and only allow multi write request against block mode. This commit also adds unit tests for isMultiWriterBlock function which validates various accesstypes and accessmodes. Signed-off-by: Humble Chirammal <hchiramm@redhat.com>		2022-01-11 19:40:22 +00:00
