* NFS: Remake nfsroot_mount as a permanent part of NFS clientChuck Lever2007-07-10
| | | | | | | | | | | | In preparation for supporting NFSv2 and NFSv3 mount option handling in the kernel NFS client, convert mount_clnt.c to be a permanent part of the NFS client, instead of built only when CONFIG_ROOT_NFS is enabled. In addition, we also replace the "struct sockaddr_in *" argument with something more generic, to help support IPv6 at some later point.

* SUNRPC: Rename rpcb_getport to be consistent with new rpcb_getport_sync nameChuck Lever2007-07-10
| | | | | | | | Clean up, for consistency. Rename rpcb_getport as rpcb_getport_async, to match the naming scheme of rpcb_getport_sync. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Rename rpcb_getport_external routineChuck Lever2007-07-10
| | | | | | | | | In preparation for handling NFS mount option parsing in the kernel, rename rpcb_getport_external as rpcb_get_port_sync, and make it available always (instead of only when CONFIG_ROOT_NFS is enabled).

* NFSv4: Defer inode revalidation when setting up a delegationTrond Myklebust2007-07-10
| | | | | | | | | Currently we force a synchronous call to __nfs_revalidate_inode() in nfs_inode_set_delegation(). This not only ensures that we cannot call nfs_inode_set_delegation from an asynchronous context, but it also slows down any call to open(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: Fix a memory leak in the auth credcache codeTrond Myklebust2007-07-10
| | | | | | | | | | | | | | The leak only affects the RPCSEC_GSS caches, since they are the only ones that are dynamically allocated... Rename the existing rpcauth_free_credcache() to rpcauth_clear_credcache() in order to better describe its role, then add a new function rpcauth_destroy_credcache() that actually frees the cache in addition to clearing it out. Also move the call to destroy the credcache in gss_destroy() to come before the rpc upcall pipe is unlinked. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: Add a downcall queue to struct rpc_inodeTrond Myklebust2007-07-10

* SUNRPC: Remove rpc_clnt->cl_countTrond Myklebust2007-07-10
| | | | | | | | | | | | The kref now does most of what cl_count + cl_user used to do. The only remaining role for cl_count is to tell us if we are in a 'shutdown' phase. We can provide that information using a single bit field instead of a full atomic counter. Also rename rpc_destroy_client() to rpc_close_client(), which reflects better what its role is these days.

* NFS4: on a O_EXCL OPEN make sure SETATTR sets the fields holding the verifierJeff Layton2007-07-10
| | | | | | | | | | | | | | | | | The Linux NFS4 client simply skips over the bitmask in an O_EXCL open call and so it doesn't bother to reset any fields that may be holding the verifier. This patch has us save the first two words of the bitmask (which is all the current client has #defines for). The client then later checks this bitmask and turns on the appropriate flags in the sattr->ia_verify field for the following SETATTR call. This patch only currently checks to see if the server used the atime and mtime slots for the verifier (which is what the Linux server uses for this). I'm not sure of what other fields the server could reasonably use, but adding checks for others should be trivial.

* Make common helpers for seq_files that work with list_headsPavel Emelianov2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many places in kernel use seq_file API to iterate over a regular list_head. The code for such iteration is identical in all the places, so it's worth introducing a common helpers. This makes code about 300 lines smaller: The first version of this patch made the helper functions static inline in the seq_file.h header. This patch moves them to the fs/seq_file.c as Andrew proposed. The vmlinux .text section sizes are as follows: 2.6.22-rc1-mm1: 0x001794d5 with the previous version: 0x00179505 with this patch: 0x00179135 The config file used was make allnoconfig with the "y" inclusion of all the possible options to make the files modified by the patch compile plus drivers I have on the test node.

* Add LZO1X algorithm to the kernelRichard Purdie2007-07-10
| | | | | | | | | | | | | | | | | | | This is a hybrid version of the patch to add the LZO1X compression algorithm to the kernel. Nitin and myself have merged the best parts of the various patches to form this version which we're both happy with (and are jointly signing off). The performance of this version is equivalent to the original minilzo code it was based on. Bytecode comparisons have also been made on ARM, i386 and x86_64 with favourable results. There are several users of LZO lined up including jffs2, crypto and reiser4 since its much faster than zlib.
