flowcache: Fix kernel panic in flow_cache_flush_task
flow_cache_flush_task references a structure member flow_cache_gc_work where it should reference flow_cache_flush_task instead. Kernel panic occurs on kernels using IPsec during XFRM garbage collection. The garbage collection interval can be shortened using the following sysctl settings: net.ipv4.xfrm4_gc_thresh=4 net.ipv6.xfrm6_gc_thresh=4 With the default settings, our productions servers crash approximately once a week. With the settings above, they crash immediately.
