Allows a cluster of computers to simultaneously use a block device that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads and writes to the block device like a local filesystem, but also uses a lock module to allow the computers coordinate their I/O so filesystem consistency is maintained. One of the nifty features of GFS is perfect consistency -- changes made to the filesystem on one machine show up immediately on all other machines in the cluster. To use the GFS2 filesystem in a cluster, you will need to enable the locking module below. Documentation and utilities for GFS2 can be found here: http://sources.redhat.com/cluster The "nolock" lock module is now built in to GFS2 by default. If you want to use the DLM, be sure to enable IPv4/6 networking. config GFS2_FS_LOCKING_DLM bool "GFS2 DLM locking" depends on (GFS2_FS!=n) && NET && INET && (IPV6 || IPV6=n) && \ CONFIGFS_FS && SYSFS && (DLM=y || DLM=GFS2_FS) help Multiple node locking module for GFS2 Most users of GFS2 will require this. It provides the locking interface between GFS2 and the DLM, which is required to use GFS2 in a cluster environment. t-rx-pump-back net-next plumbingsTobias Klauser

crypto: qat - fix bar discovery for c62x
Some accelerators of the c62x series have only two bars. This patch skips BAR0 if the accelerator does not have it. Cc: <stable@vger.kernel.org> Signed-off-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
