Merge tag 'nfs-for-3.6-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull second wave of NFS client updates from Trond Myklebust: - Patches from Bryan to allow splitting of the NFSv2/v3/v4 code into separate modules. - Fix Oopses in the NFSv4 idmapper - Fix a deadlock whereby rpciod tries to allocate a new socket and ends up recursing into the NFS code due to memory reclaim. - Increase the number of permitted callback connections. * tag 'nfs-for-3.6-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: nfs: explicitly reject LOCK_MAND flock() requests nfs: increase number of permitted callback connections. SUNRPC: return negative value in case rpcbind client creation error NFS: Convert v4 into a module NFS: Convert v3 into a module NFS: Convert v2 into a module NFS: Keep module parameters in the generic NFS client NFS: Split out remaining NFS v4 inode functions NFS: Pass super operations and xattr handlers in the nfs_subversion NFS: Only initialize the ACL client in the v3 case NFS: Create a try_mount rpc op NFS: Remove the NFS v4 xdev mount function NFS: Add version registering framework NFS: Fix a number of bugs in the idmapper nfs: skip commit in releasepage if we're freeing memory for fs-related reasons sunrpc: clarify comments on rpc_make_runnable pnfsblock: bail out partial page IO
