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": "330ab71619bacc4d4494227a6cfc9b7f5500403d", "tree": "43a9045011116f1afa506b80de1ede9872f45935", "parents": [ "a893b99be71f1d669b74f840e3a683dd077d007b" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Tue May 02 15:29:57 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Tue May 02 15:29:57 2006 +0200" }, "message": "[PATCH] vmsplice: restrict stealing a little more\n\nApply the same rules as the anon pipe pages, only allow stealing\nif no one else is using the page.\n\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "f6762b7ad8edd6abc802542ce845d3bc8adcb92f", "tree": "c941aaf7295f8efecaf42aa86112649b9b6f23a9", "parents": [ "e27dedd84c119e2f7af54fcde3293be5ad812103" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Mon May 01 20:02:05 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Mon May 01 20:02:05 2006 +0200" }, "message": "[PATCH] pipe: enable atomic copying of pipe data to/from user space\n\nThe pipe -\u003emap() method uses kmap() to virtually map the pages, which\nis both slow and has known scalability issues on SMP.
