Subject: cgroup.py: Fix potential undeclared variable
X-Git-Tag: v3.1.0~308^2~2^2~30
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c0c06b2d8eca9ecc45735f868a6054776eedf293;p=thirdparty%2Flibcgroup.git

cgroup.py: Fix potential undeclared variable

Due to the try/except and if/else paths in snapshot(),
the variable res may not be declared before reaching the
return statement.  In the case where it's undeclared,
re-raise the exception.
