From 2779e3ae39645515cb6c1126634f47c28c9e7190 Mon Sep 17 00:00:00 2001 From: Tom Tucker Date: Mon, 5 Jan 2009 11:12:52 -0600 Subject: svc: Move kfree of deferral record to common code The rqstp structure has a pointer to a svc_deferred_req record that is allocated when requests are deferred. This record is common to all transports and can be freed in common code. Move the kfree of the rq_deferred to the common svc_xprt_release function. This also fixes a memory leak in the RDMA transport which does not kfree the dr structure in it's version of the xpo_release_rqst callback. Signed-off-by: Tom Tucker Signed-off-by: J.
