From: Francis Deslauriers Date: Fri, 17 Feb 2017 16:43:07 +0000 (-0500) Subject: jjb: Replace open_enoent testcase for a more stable testcase X-Git-Url: http://git.lttng.org./?a=commitdiff_plain;h=70e85c9830a708869b110e4083ff04fd3bf3cb57;p=lttng-ci.git jjb: Replace open_enoent testcase for a more stable testcase The open_enoent testcase showed a bimodal distribution of time per event that was measurable even when tracing was disabled. This behaviour was witnessed only in cases where the open failed with an `enoent` error. Our investigation of the sys_open code pointed towards to the pathwalk in the VFS. We decided to simply change the test case to something more stable due to lack of time to put in the investigation.
