This patch series refactors the current netlink API in smc_diag module which is used for diagnostic purposes and extends the netlink API in a backward compatible way so that the extended API can provide information about SMC linkgroups, links and devices (both for SMC-R and SMC-D) and can still work with the legacy netlink API. Please note that patch 9 triggers a checkpatch warning because a comment line was added using the style of the already existing comment block. v2: In patch 10, add missing include to uapi header smc_diag.h. v3: Apply code style recommendations from review comments. Instead of using EXPORTs to allow the smc_diag module to access data of the smc module, introduce struct smc_diag_ops and let smc_diag access the required data using function pointers.
