+[PATCH] modules: lvm: fix activationskip check
+
+Fix boot breakage due to the activationskip check introduced in
+cfa365a32d47 ("lvm: Don't activate LVs with activationskip set").
+
+In 'man 8 lvs', it is stated that LVs with activationskip set, will have
+a "k" flag in their lvs attribute listing.
+
+The current implementation excludes LVs which do not have the "k"
+flag set. This leads to the activation of LVs with the activationskip
+set and the exclusion of LVs with no activationskip set: the check's
+logic is inverted.
+
+Fix this issue by skipping those LVs that have the "k" flag in their
+attributes.
