Subject: meson: add fuzz-tests= option
X-Git-Tag: v246-rc1~306^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c56463fdb40ba505b807739b023e9489c6ac182d;p=thirdparty%2Fsystemd.git

meson: add fuzz-tests= option

The slow-tests= option already enables fuzzers as well, however, this
option can't be used in the "fully sanitized" runs, as certain slow
tests are affected by the performance quite significantly.

This option allows us to enable only fuzzers without the slow tests to
meet the needs of such runs.
