Subject: sunrpc: Pass xprt to cached get/put routines
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3be4479fdf2fb7eb17a4592917ae4b536058b0c7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sunrpc: Pass xprt to cached get/put routines

They do not require the rqst actually and having the xprt simplifies
further patching.
