From: Gabriel-Andrew Pollo-Guilbert Date: Mon, 29 Jul 2019 15:14:26 +0000 (-0400) Subject: Fix: remove uninitialised value X-Git-Tag: v2.9.6~3 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=acafe8d878bdbfd391b47b5b8a525a82a6e9702b;p=lttng-ust.git Fix: remove uninitialised value Commit 973eac638e4fd introduces an uninitialised value that may prevent shared memory from being allocated. The compiler didn't give any warning because the pointer to the value is sent to a function that don't do anything with it. We simply pass NULL to that function.
