Subject: fincore: (tests) fix tmpfs detection for out-of-tree builds
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=187122ce130e49420bca7530eee0bffd198ba04f;p=thirdparty%2Futil-linux.git

fincore: (tests) fix tmpfs detection for out-of-tree builds

The tmpfs check used $PWD which points to the source directory, not
to the output directory where test files are actually created. When
tests are run with --builddir on tmpfs (e.g. /tmp), the check fails
to detect it and the test produces wrong results because O_DIRECT
has no effect on tmpfs.

Use $TS_OUTDIR instead, which is the actual directory where dd
creates test files and fincore inspects them.
