From f7d4668155245d90470f591576b6593e0f077fcb Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 1 Oct 2018 14:26:24 -0400 Subject: [PATCH] xprtrdma: Don't disable BH's in backchannel server Clean up: This code was copied from xprtsock.c and backchannel_rqst.c. For rpcrdma, the backchannel server runs exclusively in process context, thus disabling bottom-halves is unnecessary.
