config FSCACHE tristate "General filesystem local caching manager" help This option enables a generic filesystem caching manager that can be used by various network and other filesystems to cache data locally. Different sorts of caches can be plugged in, depending on the resources available. See Documentation/filesystems/caching/fscache.txt for more information. config FSCACHE_STATS bool "Gather statistical information on local caching" depends on FSCACHE && PROC_FS help This option causes statistical information to be gathered on local caching and exported through file: /proc/fs/fscache/stats The gathering of statistics adds a certain amount of overhead to execution as there are a quite a few stats gathered, and on a multi-CPU system these may be on cachelines that keep bouncing between CPUs. On the other hand, the stats are very useful for debugging purposes. Saying 'Y' here is recommended. See Documentation/filesystems/caching/fscache.txt for more information. config FSCACHE_HISTOGRAM bool "Gather latency information on local caching" depends on FSCACHE && PROC_FS help This option causes latency information to be gathered on local caching and exported through file: /proc/fs/fscache/histogram The generation of this histogram adds a certain amount of overhead to execution as there are a number of points at which data is gathered, and on a multi-CPU system these may be on cachelines that keep bouncing between CPUs. On the other hand, the histogram may be useful for debugging purposes. Saying 'N' here is recommended. See Documentation/filesystems/caching/fscache.txt for more information. config FSCACHE_DEBUG bool "Debug FS-Cache" depends on FSCACHE help This permits debugging to be dynamically enabled in the local caching management module. If this is set, the debugging output may be enabled by setting bits in /sys/modules/fscache/parameter/debug. See Documentation/filesystems/caching/fscache.txt for more information. config FSCACHE_OBJECT_LIST bool "Maintain global object list for debugging purposes" depends on FSCACHE && PROC_FS help Maintain a global list of active fscache objects that can be retrieved through /proc/fs/fscache/objects for debugging purposes 'qt'>

net/sched: cls_flower: Correct matching on ICMPv6 code
When matching on the ICMPv6 code ICMPV6_CODE rather than ICMPV4_CODE attributes should be used. This corrects what appears to be a typo. Sample usage: tc qdisc add dev eth0 ingress tc filter add dev eth0 protocol ipv6 parent ffff: flower \ indev eth0 ip_proto icmpv6 type 128 code 0 action drop Without this change the code parameter above is effectively ignored.
