The root dentry set\nstarts off as an anonymous dentry if we don\u0027t already have the dentry for its\ninode, otherwise it simply returns the dentry we already have.\n\nWe may thus end up with several trees of dentries in the superblock, and if at\nsome later point one of anonymous tree roots is discovered by normal filesystem\nactivity to be located in another tree within the superblock, the anonymous\nroot is named and materialises attached to the second tree at the appropriate\npoint.\n\nWhy do it this way? Why not pass an extra argument to the mount() syscall to\nindicate the subpath and then pathwalk from the server root to the desired\ndirectory? You can\u0027t guarantee this will work for two reasons:\n\n (1) The root and intervening nodes may not be accessible to the client.\n\n With NFS2 and NFS3, for instance, mountd is called on the server to get\n the filehandle for the tip of a path. mountd won\u0027t give us handles for\n anything we don\u0027t have permission to access, and so we can\u0027t set up NFS\n inodes for such nodes, and so can\u0027t easily set up dentries (we\u0027d have to\n have ghost inodes or something).\n\n With this patch we don\u0027t actually create dentries until we get handles\n from the server that we can use to set up their inodes, and we don\u0027t\n actually bind them into the tree until we know for sure where they go.\n\n (2) Inaccessible symbolic links.\n\n If we\u0027re asked to mount two exports from the server, eg:\n\n\tmount warthog:/warthog/aaa/xxx /mmm\n\tmount warthog:/warthog/bbb/yyy /nnn\n\n We may not be able to access anything nearer the root than xxx and yyy,\n but we may find out later that /mmm/www/yyy, say, is actually the same\n directory as the one mounted on /nnn. What we might then find out, for\n example, is that /warthog/bbb was actually a symbolic link to\n /warthog/aaa/xxx/www, but we can\u0027t actually determine that by talking to\n the server until /warthog is made available by NFS.\n\n This would lead to having constructed an errneous dentry tree which we\n can\u0027t easily fix. We can end up with a dentry marked as a directory when\n it should actually be a symlink, or we could end up with an apparently\n hardlinked directory.\n\n With this patch we need not make assumptions about the type of a dentry\n for which we can\u0027t retrieve information, nor need we assume we know its\n place in the grand scheme of things until we actually see that place.\n\nThis patch reduces the possibility of aliasing in the inode and page caches for\ninodes that may be accessed by more than one NFS export. It also reduces the\nnumber of superblocks required for NFS where there are many NFS exports being\nused from a server (home directory server + autofs for example).\n\nThis in turn makes it simpler to do local caching of network filesystems, as it\ncan then be guaranteed that there won\u0027t be links from multiple inodes in\nseparate superblocks to the same cache file.\n\nObviously, cache aliasing between different levels of NFS protocol could still\nbe a problem, but at least that gives us another key to use when indexing the\ncache.\n\nThis patch makes the following changes:\n\n (1) The server record construction/destruction has been abstracted out into\n its own set of functions to make things easier to get right. These have\n been moved into fs/nfs/client.c.\n\n All the code in fs/nfs/client.c has to do with the management of\n connections to servers, and doesn\u0027t touch superblocks in any way; the\n remaining code in fs/nfs/super.c has to do with VFS superblock management.\n\n (2) The sequence of events undertaken by NFS mount is now reordered:\n\n (a) A volume representation (struct nfs_server) is allocated.\n\n (b) A server representation (struct nfs_client) is acquired. This may be\n \t allocated or shared, and is keyed on server address, port and NFS\n \t version.\n\n (c) If allocated, the client representation is initialised. The state\n \t member variable of nfs_client is used to prevent a race during\n \t initialisation from two mounts.\n\n (d) For NFS4 a simple pathwalk is performed, walking from FH to FH to find\n \t the root filehandle for the mount (fs/nfs/getroot.c). For NFS2/3 we\n \t are given the root FH in advance.\n\n (e) The volume FSID is probed for on the root FH.\n\n (f) The volume representation is initialised from the FSINFO record\n \t retrieved on the root FH.\n\n (g) sget() is called to acquire a superblock. This may be allocated or\n \t shared, keyed on client pointer and FSID.\n\n (h) If allocated, the superblock is initialised.\n\n (i) If the superblock is shared, then the new nfs_server record is\n \t discarded.\n\n (j) The root dentry for this mount is looked up from the root FH.\n\n (k) The root dentry for this mount is assigned to the vfsmount.\n\n (3) nfs_readdir_lookup() creates dentries for each of the entries readdir()\n returns; this function now attaches disconnected trees from alternate\n roots that happen to be discovered attached to a directory being read (in\n the same way nfs_lookup() is made to do for lookup ops).\n\n The new d_materialise_unique() function is now used to do this, thus\n permitting the whole thing to be done under one set of locks, and thus\n avoiding any race between mount and lookup operations on the same\n directory.\n\n (4) The client management code uses a new debug facility: NFSDBG_CLIENT which\n is set by echoing 1024 to /proc/net/sunrpc/nfs_debug.\n\n (5) Clone mounts are now called xdev mounts.\n\n (6) Use the dentry passed to the statfs() op as the handle for retrieving fs\n statistics rather than the root dentry of the superblock (which is now a\n dummy).\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "cf6d7b5de8535a9f0088c5cc28ee2dae87371b4a", "tree": "815aecb371fc5b702c209bbda550e950e2bd1b04", "parents": [ "5006a76cca8f86c6975c16fcf67e83b8b0eee2b6" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Aug 22 20:06:12 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Sep 22 23:24:36 2006 -0400" }, "message": "NFS: Start rpciod in server common management\n\nStart rpciod in the server common (nfs_client struct) management code rather\nthan in the superblock management code.

An array for\npages is already allocated for us by nfs_readdata_alloc() (and the write\nand commit equivalents).\n\nThis is also required for adding support for vectored I/O to the NFS direct\nI/O path.\n\nThe original reason to pin the user buffer and allocate all the NFS data\nstructures before trying to schedule I/O was to ensure all needed resources\nare allocated on the client before starting to send requests. This reduces\nthe chance that resource exhaustion on the client will cause a short read\nor write.\n\nOn the other hand, for an application making very large application I/O\nrequests, this means that it will be nearly impossible for the application\nto make forward progress on a resource-limited client.\n\nThus, moving the buffer pinning functionality into the I/O scheduling\nloops should be good for scalability.

For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "81039f1f204a0fd2952112a240284e114f1a25e6", "tree": "511625e9ea5361dc240ef0540aff7e5cde1551cb", "parents": [ "f7b422b17ee5ee4920e8ae24a6ad04bf3481ce72" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jun 09 09:34:34 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jun 09 09:34:34 2006 -0400" }, "message": "NFS: Display the chosen RPCSEC_GSS security flavour in /proc/mounts\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "f7b422b17ee5ee4920e8ae24a6ad04bf3481ce72", "tree": "4ae8372762efc092ceb4f884b57cad1efe6594de", "parents": [ "4e5ccf60c5aa79d325c123f47d288a068166f389" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Jun 09 09:34:33 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jun 09 09:34:33 2006 -0400" }, "message": "NFS: Split fs/nfs/inode.c\n\nAs fs/nfs/inode.c is rather large, heterogenous and unwieldy, the attached\npatch splits it up into a number of files:\n\n (*) fs/nfs/inode.c\n\n Strictly inode specific functions.\n\n (*) fs/nfs/super.c\n\n Superblock management functions for NFS and NFS4, normal access, clones\n and referrals.
