Subject: [PATCH] test/pipe-bug: ignore -ENOMEM on ring creation
|
|
|
|
Since this test case sets up and tears down a ton of rings, this can
|
|
result in the deferred freeing/unaccounting causing spurious -ENOMEM
|
|
returns. This is expected if the system is configured to be tight on
|
|
locked memory (ulimit -l). If this happens, inject a small delay and
|
|
just have it retry.
