[DTrace-devel] [PATCH] test: tst.ustackdepth-bug25949692.d timeout

[eugene.loh at oracle.com]

From: Eugene Loh <eugene.loh at oracle.com>

The test would timeout on some systems -- e.g., an ARM VM running
OL8.  Since it relied on syscall::ioctl:entry firing but there was
no trigger, there was no guarantee that the test would complete in
any particular time.

Remove the test.  Its scope was very narrow (testing only that
ustackdepth was neither 1 nor 0, in response to a particular bug)
and focused on behavior in an implementation that is no longer used.
Meanwhile, this built-in variable is tested more rigorously by other
tests that, e.g., check the ustackdepth value against the actual
depth of the ustack.
