commit 449070996ce6e5b1fc3b66538f04ab37c2c0591f
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I64YCA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=449070996ce6e5b1fc3b66538f04ab37c2c0591f



--------------------------------

commit cba04f31 upstream.

For modules, names from kallsyms__parse() contain the module name which
meant that module symbols did not match exactly by name.

Fix by matching the name string up to the separating tab character.
