[PATCH 1/2] New tests testing the addition of bitmaps

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Jes Sorensen <Jes.Sorensen@xxxxxxxxxx>

This set of tests verifies that it is possible to add an internal
bitmap to an existing array, and that the device can be written to
after the bitmap is added. This should catch cases such as the one
fixed by 4474ca42e2577563a919fd3ed782e2ec55bf11a2
