Subject: Create test name from most recently used test number
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b1e29e775872c30282331d02ca53ec6529ad79d2;p=users%2Fsagi%2Fblktests.git

Create test name from most recently used test number

The 'new' script can inadvertently use a test name that was removed, ex
nvme/001, which may create confusion if identically-named tests exist
among different versions. Instead, generate a test name at the numerical
tail end of the test group.
