LINUX 5.9: Remove HAVE_UNLOCKED_IOCTL/COMPAT_IOCTL
Linux-5.9-rc1 commit 'fs: remove the HAVE_UNLOCKED_IOCTL and
HAVE_COMPAT_IOCTL defines' (
4e24566a) removed the two referenced macros
from the kernel.
The support for unlocked_ioctl and compat_ioctl were introduced in
Linux 2.6.11.
Remove references to HAVE_UNLOCKED_IOCTL and HAVE_COMPAT_IOCTL using
the assumption that they were always defined.
Notes:
With this change, building against kernels 2.6.10 and older will fail.
RHEL4 (EOL in March 2017) used a 2.6.9 kernel. RHEL5 uses a 2.6.18
kernel.
In linux-2.6.33-rc1 the commit messages for "staging: comedi:
Remove check for HAVE_UNLOCKED_IOCTL" (
00a1855c) and "Staging: comedi:
remove check for HAVE_COMPAT_IOCTL" (
5d7ae225) both state that all new
kernels have support for unlocked_ioctl/compat_ioctl so the checks can
be removed along with removing support for older kernels.
