Subject: Allow compat_ioctl.c to compile without CONFIG_NET
X-Git-Tag: v2.6.22-rc1~106
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d9de2622bd4fd29cab4ef7db66a9f916cb38e032;p=linux-2.6

Allow compat_ioctl.c to compile without CONFIG_NET

A small regression appears to have been introduced in the recent patch
"cleanup compat ioctl handling", which was included in Linus' tree after
2.6.20.

siocdevprivate_ioctl() is no longer defined if CONFIG_NET is undefined,
whereas previously it was a dummy function in this case.

This causes compilation with CONFIG_COMPAT but without CONFIG_NET to fail.

fs/compat_ioctl.c: In function `compat_sys_ioctl':
fs/compat_ioctl.c:3571: warning: implicit declaration of function `siocdevprivate_ioctl'
