Subject: [PATCH 18/20] Fix elf/tst-dlmopen-twice to support enough link namespaces
Date: Thu, 27 Oct 2022 16:33:48 +0100 [thread overview]
Message-ID: <1adc193aeb267bdb147428b747e66c77cfd447d0.1666877952.git.szabolcs.nagy@arm.com> (raw)
In-Reply-To: <cover.1666877952.git.szabolcs.nagy@arm.com>
The test dlmopens 10 namespaces recursively, which requires a glibc
tunable setting, otherwise it may run out of static TLS.
