If we want to add some info to errp (by error_prepend() or
error_append_hint()), we must use the ERRP_AUTO_PROPAGATE macro.
Otherwise, this info will not be added when errp == &fatal_err
(the program will exit prior to the error_append_hint() or
error_prepend() call). Fix such cases.
If we want to check error after errp-function call, we need to
introduce local_err and than propagate it to errp. Instead, use
ERRP_AUTO_PROPAGATE macro, benefits are:
1. No need of explicit error_propagate call
2. No need of explicit local_err variable: use errp directly
3. ERRP_AUTO_PROPAGATE leaves errp as is if it's not NULL or
&error_fatel, this means that we don't break error_abort
(we'll abort on error_set, not on error_propagate)
This commit (together with its neighbors) was generated by
for f in $(git grep -l errp \*.[ch]); do \
spatch --sp-file scripts/coccinelle/auto-propagated-errp.cocci \
--macro-file scripts/cocci-macro-file.h --in-place --no-show-diff $f; \
done;
then fix a bit of compilation problems: coccinelle for some reason
leaves several
f() {
...
goto out;
...
out:
}
patterns, with "out:" at function end.
then
./python/commit-per-subsystem.py MAINTAINERS "$(< auto-msg)"
(auto-msg was a file with this commit message)
Still, for backporting it may be more comfortable to use only the first
command and then do one huge commit.
