Subject: [PATCH 42/83] mdadm/test: Add a mode to repeat specified tests
|
|
|
cd8c44 |
|
|
|
cd8c44 |
Many tests fail infrequently or rarely. To help find these, add
|
|
|
cd8c44 |
an option to run the tests multiple times by specifying --loop=N.
|
|
|
cd8c44 |
|
|
|
cd8c44 |
If --loop=0 is specified, the test will be looped forever.
