Subject: compat: add struct compat_ifreq etc to compat.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2dceba14ef0e62738d58777a1bd4018130d47a74;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

compat: add struct compat_ifreq etc to compat.h

In order to move socket ioctl conversion code into multiple
places in the socket code, we need a common defintion of
the data structures it uses.

Also change the name from ifreq32 to compat_ifreq to
follow the naming convention for compat.h
