From 40abf9be8f52d440e442206182916e3dcc68f722 Mon Sep 17 00:00:00 2001 From: Jerry Hoemann Date: Mon, 11 Apr 2016 15:02:28 -0700 Subject: [PATCH] libnvdimm: increase max envelope size for ioctl nd_ioctl() must first read in the fixed sized portion of an ioctl so that it can then determine the size of the variable part. Prepare for ND_CMD_CALL calls which have larger fixed portion envelope.
