Calling src/<file> without path '$here' may cause the problem that
the file cannot be found.
For example, Running generic/192 with overlayfs(Let ubifs as base
fs) yields the following output:
generic/192 - output mismatch
QA output created by 192
sleep for 5 seconds
test
+./common/rc: line 316: src/t_dir_type: No such file or directory
delta1 is in range
delta2 is in range
...
When the use case fails, the call stack in generic/192 is:
local unknowns=$(src/t_dir_type $dir u | wc -l) common/rc
_supports_filetype common/rc
_overlay_mount common/overlay
_overlay_test_mount common/overlay
_test_mount common/rc
_test_cycle_mount generic/192
Before _test_cycle_mount() being invoked, generic/192 executed 'cd
/' to change work dir from 'xfstests-dev' to '/', so src/t_dir_type
was not found.
[Eryu: some tests run src/<file> as regular user, don't add $here
prefix in such case, as a regular user may have no search permission
on $here]
