> Sorry, I do not know how to use the SmPL script. I would like to try again to make you more familiar with applications of the Coccinelle software. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/dev-tools/coccinelle.rst?id=b4f633221f0aeac102e463a4be46a643b2e3b819#n9 Another small example according to a script for the semantic patch language: @display@ expression e, x; statement is, es; type t; @@ *e = (t) ioremap(...) ... when != if( \( !e \| e == NULL \| unlikely( \( !e \| e == NULL \) ) \| WARN_ON( \( !e \| e == NULL \) ) \) ) is else es when != iounmap(e) return x; >> Would you like to let any more source code analysis tools help you >> to find remaining update candidates? >> > yes, but I think the source code analysis tools only can found the simple > repetitive issue. The shown analysis approach can point 127 source files out from the software “Linux next-20200423”. These files contain function implementations which might need further development considerations. > and need spend some time learning to use it. You came along a few files where you noticed questionable source code. Would you become interested to find similar places for another check? elfring@Sonne:~/Projekte/Linux/next-patched> XX=$(date) && spatch --no-loops --timeout 12 -j 4 --chunksize 1 -dir ~/Projekte/Linux/next-patched ~/Projekte/Coccinelle/janitor/show_questionable_ioremap_usage3.cocci > ~/Projekte/Bau/Linux/scripts/Coccinelle/ioremap/20200423/show_questionable_ioremap_usage3.diff 2> ~/Projekte/Bau/Linux/scripts/Coccinelle/ioremap/20200423/show_questionable_ioremap_usage3-errors.txt; YY=$(date) && echo "$XX | $YY" Fr 24.

How do you think about to reduce efforts for manual code inspection? Regards, Markus
