      "message": "mm: merge populate and nopage into fault (fixes nonlinear)\n\nNonlinear mappings are (AFAIKS) simply a virtual memory concept that encodes\nthe virtual address -\u003e file offset differently from linear mappings.\n\n-\u003epopulate is a layering violation because the filesystem/pagecache code\nshould need to know anything about the virtual memory mapping.  The hitch here\nis that the -\u003enopage handler didn\u0027t pass down enough information (ie.  pgoff).\n But it is more logical to pass pgoff rather than have the -\u003enopage function\ncalculate it itself anyway (because that\u0027s a similar layering violation).\n\nHaving the populate handler install the pte itself is likewise a nasty thing\nto be doing.\n\nThis patch introduces a new fault handler that replaces -\u003enopage and\n-\u003epopulate and (later) -\u003enopfn.  Most of the old mechanism is still in place\nso there is a lot of duplication and nice cleanups that can be removed if\neveryone switches over.\n\nThe rationale for doing this in the first place is that nonlinear mappings are\nsubject to the pagefault vs invalidate/truncate race too, and it seemed stupid\nto duplicate the synchronisation logic rather than just consolidate the two.\n\nAfter this patch, MAP_NONBLOCK no longer sets up ptes for pages present in\npagecache.

      "message": "[PATCH] VFS: Permit filesystem to override root dentry on mount\n\nExtend the get_sb() filesystem operation to take an extra argument that\npermits the VFS to pass in the target vfsmount that defines the mountpoint.\n\nThe filesystem is then required to manually set the superblock and root dentry\npointers.  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"
