Subject: test/init-mem: zero the ringbuf memory
|
||
|
|
References: fix-test-crash
|
||
|
|
Patch-mainline: Submitted, #1293
|
||
|
|
|
||
|
|
This is a similar fix to commit 8100d7b5f862 (test/buf-ring-nommap: zero
|
||
|
|
the ringbuf memory). The same is needed for test/init-mem as it crashes
|
||
|
|
with MALLOC_PERTURB_=69 too.
|
||
|
|
|
||
|
|
So zero the ringbuf memory after posix_memalign() too.
|
||
|
|
|
||
|
|
Fixes #1291.
