For basically any Normally I do testing by following methods, 1) normal file system testing on it 2) long time I/O pressure e.g. at least 48 hours 3) deploy on my working machines with real workload for weeks Current tests are not automatically. And I will integreate Kent's test tools in. > other maintained subsystem we'd have a maintainer jump on verity fixes > like this ASAP and test them. > Before I work on it, I want to know the author already ran and tested the patch firstly. Normally I won't test any patches posted on mailing list. Thanks. Coly Li
