From: Thomas Huth Date: Wed, 4 Dec 2019 16:46:12 +0100 Subject: iotests: Provide a function for checking the creation of huge files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Git-commit: 30729ae93b7e123e472a2d42792134ae39bf9df0 Some tests create huge (but sparse) files, and to be able to run those tests in certain limited environments (like CI containers), we have to check for the possibility to create such files first. Thus let's introduce a common function to check for large files, and replace the already existing checks in the iotests 005 and 220 with this function.
