init_overlay_changeset() stores the number of initialized fragments
\nin ovcs->count only on full success. When find_target() or the
\n__symbols__ lookup fails partway through, the target and overlay
\nreferences taken for the fragments initialized so far are never
\ndropped: free_overlay_changeset() bounds its cleanup loop by
\novcs->count, which is still 0.<\/p>\n
Store the running count on the error path so free_overlay_changeset()
\nputs whatever was set up. The store is guarded by ovcs->fragments
\nbecause on the allocation-failure path cnt still holds the counting
\npass total while there is no fragments array; everywhere else cnt
\nonly counts fully-initialized fragments.<\/p>\n","protected":false},"excerpt":{"rendered":"
