From: Nils Carlson Date: Tue, 17 May 2011 13:16:47 +0000 (+0200) Subject: New fast-exit test-case X-Git-Tag: v0.13~3 X-Git-Url: https://git.liburcu.org/?p=ust.git;a=commitdiff_plain;h=46cec820d380796882540bf5a8904949d86e3515 New fast-exit test-case A fast-exit test-case that just writes one marker and exits, tests that the consumer daemon maps the buffers before the program exits. Exiting is tested both by normal return and by commiting suicide (SIGKILL to self).
