// SkipInvalidDriverPatternCombination will skip tests if the combination of driver, and testpattern
// is not compatible to be tested. This function will be called in the RegisterTests() to make
// sure all the testsuites we defined are valid.
//
// Whether it needs to be skipped is checked by following steps:
// 0. Check with driver SkipUnsupportedTest
// 1. Check if volType is supported by driver from its interface
// 2. Check if fsType is supported
//
// Test suites can also skip tests inside their own skipUnsupportedTests function or in
// individual tests.
