Subject: lib: test-file-cache - Ignore RLIMIT_AS enforcement failure
X-Git-Tag: 2.4.1~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a12707f100d82479bd957aa7fcf3a4e5d66ce9fd;p=thirdparty%2Fdovecot%2Fcore.git

lib: test-file-cache - Ignore RLIMIT_AS enforcement failure

If the OS does not respect RLIMIT_AS here, lets skip all the rest of
the tests.

This happens at least with qemu/aarch64.
