Subject: iotests: Provide a function for checking the creation of huge files

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.
