Subject: [PATCH 50/50] tests: Add t4201 to test partprobe with 1025 devices
|
|
|
fc4a62 |
|
|
|
fc4a62 |
This makes sure partprobe is closing the device and doesn't run out of
|
|
|
fc4a62 |
file descriptors. Uses scsi_debug to create 1025 devices (descriptor
|
|
|
fc4a62 |
limit is 1024).
|
|
|
fc4a62 |
|
|
|
fc4a62 |
Also adds partprobe to the TESTS_ENVIRONMENT PATH, otherwise it will use
|
|
|
fc4a62 |
the partprobe installed on the system when running the tests.
