config JBD2 tristate select CRC32 select CRYPTO select CRYPTO_CRC32C help This is a generic journaling layer for block devices that support both 32-bit and 64-bit block numbers. It is currently used by the ext4 and OCFS2 filesystems, but it could also be used to add journal support to other file systems or block devices such as RAID or LVM. If you are using ext4 or OCFS2, you need to say Y here. If you are not using ext4 or OCFS2 then you will probably want to say N. To compile this device as a module, choose M here. The module will be called jbd2. If you are compiling ext4 or OCFS2 into the kernel, you cannot compile this code as a module. config JBD2_DEBUG bool "JBD2 (ext4) debugging support" depends on JBD2 help If you are using the ext4 journaled file system (or potentially any other filesystem/device using JBD2), this option allows you to enable debugging output while the system is running, in order to help track down any problems you are having. By default, the debugging output will be turned off. If you select Y here, then you will be able to turn on debugging with "echo N > /sys/module/jbd2/parameters/jbd2_debug", where N is a number between 1 and 5. The higher the number, the more debugging output is generated. To turn debugging off again, do "echo 0 > /sys/module/jbd2/parameters/jbd2_debug". /form> net-next plumbingsTobias Klauser

Merge branch 'mlxsw-offload-mc-flood'
Jiri Pirko says: ==================== mlxsw: Offload MC flood for unregister MC Nogah says: When multicast is enabled, the Linux bridge floods unregistered multicast packets only to ports connected to a multicast router. Devices capable of offloading the Linux bridge need to be made aware of such ports, for proper flooding behavior. On the other hand, when multicast is disabled, such packets should be flooded to all ports. This patchset aims to fix that, by offloading the multicast state and the list of multicast router ports. The first 3 patches adds switchdev attributes to offload this data. The rest of the patchset add implementation for handling this data in the mlxsw driver. The effects this data has on the MDB (namely, when the multicast is disabled the MDB should be considered as invalid, and when it is enabled, a packet that is flooded by it should also be flooded to the multicast routers ports) is subject of future work. Testing of this patchset included: Sending 3 mc packets streams, LL, register and unregistered, and checking that they reached only to the ports that should have received them. The configs were: mc disabled, mc without mc router ports and mc with fixed router port. It was checked for vlan aware bridge, vlan unaware bridge and vlan unaware bridge with another vlan unaware bridge on the same machine ==================== Signed-off-by: David S.
