the older rbd images on the chain to avoid
issue in krbd.The limit is in krbd since it

snapshot ids for an image.
The max limit is 510 as per

added Hardlimit and Softlimit flags for cephcsi
arguments. When the Softlimit is reached cephcsi
will start a background task to flatten the rbd
image and return success and if the hardlimit
is reached it will start a background task
to flatten the rbd image and return ready
to use as false to make sure that the image
will not be used until it is flatten.

understand what component to mention in the prefix of the subject in

The internal/ directory in Go has a special meaning, and indicates that
those packages are not meant for external consumption. Ceph-CSI does
provide public APIs for other projects to consume. There is no plan to
keep the API of the internally used packages stable.

In (standard, non-privileged) container environments the /sys/fs/cgroup
mountpoint is not available. This would cause the tests to fail, as
TestGetPIDLimit() tries to write to the cgroup configuration.
The test will work when run as root on a privileged container or
directly on a host (as Travis CI does).
Setting the CEPH_CSI_RUN_ALL_TESTS environment variable to a non-empty
value will cause the test to be executed.
