AI review asks many questions: https://sashiko.dev/#/patchset/cover.1774591179.git.sayalip@linux.ibm.com I never knew about that bash line continuation thing. hp2:/home/akpm> cat t.sh foo=\ bar echo $foo hp2:/home/akpm> bash t.sh t.sh: line 3: bar: command not found Huh. But it presumably passed your testing so confused. I don't want to risk breaking selftests so I'll set v3 aside until you're confident we should proceed. Thanks.
