If you run coccicheck with V=1 and COCCI=, you will see a strange
path to the semantic patch file. For example, run the following:
$ make V=1 COCCI=scripts/coccinelle/free/kfree.cocci coccicheck
[ snip ]
The semantic patch that makes this report is available
in scriptcoccinelle/free/kfree.cocci.
Notice "s/" was dropped from "scripts/coccinelle/free/kfree.cocci".
When running coccicheck without O=, $srctree is expanded to ".", which
represents one arbitrary character in the regular expression. Using
sed is not a good choice here. Strip $srctree/ simply without sed.

Did you review/test this patch?
or point out something about existing code?
The error message points to line 63:
COCCIINCLUDE=${LINUXINCLUDE//-I/-I }
My code
FILE=${COCCI#$srctree/}
works on dash.
I believe your post does not block my patch.
Actually, scripts/coccicheck contains three lines
that depend on bash.
line 63: COCCIINCLUDE=${LINUXINCLUDE//-I/-I }
line 64: COCCIINCLUDE=${COCCIINCLUDE// -include/ --include}
line 134: if [[ $? -ne 0 ]]; then
They are legitimate because I see the correct shebang #!/bin/bash
on the top of this script.
CONFIG_SHELL is not described in Documentation/kbuild/kbuild.txt
so Kbuild does not expect CONFIG_SHELL overridden from the command line.
(at least for now).
Some sell scripts in kernel tree are specified with "#!/bin/sh"
and others with "#!/bin/bash"
Both of the cases are invoked with CONFIG_SHELL in Kbuild,
so several scripts give error with CONFIG_SHELL=dash.
For example,
masahiro@grover:~/ref/linux$ make CONFIG_SHELL=dash tags
GEN tags
./scripts/tags.sh: 159: ./scripts/tags.sh: Syntax error: "(" unexpected
make: *** [tags] Error 2
Of course, it will be possible to improve this situation if we like,
but should be discussed in a new thread since this is
about Kbuild infrastructure, not a coccinelle-related topic.
