Get rid of the `get_used_prop` function. `get_prop used` works fine. Fix the comment describing the function parameters. The type does not have a default, and mntp is also used for ext2. Rename the variable for the number of copies from `copy` to `copies`. Use a `case` statement to match the type parameter, order the cases alphabetically, and add a little sanity checking for good measure. Use eval to make sure the output of commands is silenced rather than the log messages when redirecting output to /dev/null. Simplify cases where zfs requires special behavior. Don't allow the test to loop forever in the event space usage does not change. Bail out of the loop and fail after an arbitrary number of iterations. Add more information to the log message when the test fails, to help debugging. Signed-off-by: Ryan Moeller <[email protected]>

Indeed, the space used was not changing. I don't think I figured out exactly the reason for that, but broadly it was because our zvol integration was broken / incomplete. |

Motivation and Context
This test was stuck in an infinite loop, which caused me to stare at the code for quite a while to figure out why.
Description
Get rid of the
get_used_propfunction.get_prop usedworks fine.Fix the comment describing the function parameters. The type does not have a default, and mntp is also used for ext2.
Rename the variable for the number of copies from
copytocopies.Use a
casestatement to match the type parameter, order the cases alphabetically, and add a little sanity checking for good measure.Use eval to make sure the output of commands is silenced rather than the log messages when redirecting output to /dev/null.
Simplify cases where zfs requires special behavior.
Don't allow the test to loop forever in the event space usage does not change. Bail out of the loop and fail after an arbitrary number of iterations.
Add more information to the log message when the test fails, to help debugging.
