Subject: Fix: Move pipe override to the arch specific pointers_override.h
X-Git-Tag: v2.8.0-rc1~78
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=5539ecc8f6ab0a597e5125ff6a16d1a39017417f;p=lttng-modules.git

Fix: Move pipe override to the arch specific pointers_override.h

The MIPS architecture has a non-standard calling convention for pipe()
and cannot use the provided override for the pipe event.
