From fe0da4e5e8c661663297315da0fa47532ca5f362 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 15 Mar 2019 17:13:06 +0100 Subject: compat_ioctl: bsg: add handler bsg_ioctl() calls into scsi_cmd_ioctl() for a couple of generic commands and relies on fs/compat_ioctl.c to handle it correctly in compat mode. Adding a private compat_ioctl() handler avoids that round-trip and lets us get rid of the generic emulation once this is done. Note that bsg implements an SG_IO command that is different from the other drivers and does not need emulation.
