Subject: Fix: is_compat_task !CONFIG_COMPAT compile error on kernels >= 3.3
X-Git-Tag: v2.0.1~1
X-Git-Url: http://git.lttng.org/?p=lttng-modules.git;a=commitdiff_plain;h=bfa949bf033f588fdd6f80ad8b50220ea153446e

Fix: is_compat_task !CONFIG_COMPAT compile error on kernels >= 3.3

The Linux kernel already defines a is_compat_task()   (0) when
!CONFIG_COMPAT since kernel 3.3, so if we see it is already defined,
don't redefine it.

Closes #195
