Subject: [PATCH 0/2] testing/selftests: Have instance test stress instances more
Date: Thu, 29 Oct 2026 16:28:49 -0400 [thread overview]
Message-ID: <20261029202849.245864353@kernel.org> (raw)
I found that the instance test doesn't actually stress the creation
and deletion of instances while reading them as I thought it did.
This was due to the rmdir failing to remove the instance because it
was busy (by the reads that were happening).
Make the tests do 10 creations and removals while reading the instance
and mkae sure the removal succeeds.
Also add reading of more files that were not tested before.
