+Subject: [PATCH] RPCoRDMA: Frame end cleanup for global write offsets
+
+Add a frame end routine for a global which is assigned to packet
+scoped memory. It really should be made proto data, but is used
+in a function in the header (that doesn't take the packet info
+struct as an argument) and this fix needs to be made in stable
+branches.
+
+Fix #18852
