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": "2edc322d420a4cec8dbc184a1220ecd7fa9f8ae6", "tree": "e7be2cf442626316b6b6fb212960fe1f77ff2725", "parents": [ "be967b7e2f7747a5ebf2a07ee627d9338491e784", "2f3243aebd8df4d9eecaeca04bbff6c7dbfb2142" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jun 20 14:51:22 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jun 20 14:51:22 2006 -0700" }, "message": "Merge git://git.infradead.org/~dwmw2/rbtree-2.6\n\n* git://git.infradead.org/~dwmw2/rbtree-2.6:\n [RBTREE] Switch rb_colour() et al to en_US spelling of \u0027color\u0027 for consistency\n Update UML kernel/physmem.c to use rb_parent() accessor macro\n [RBTREE] Update hrtimers to use rb_parent() accessor macro.\n [RBTREE] Add explicit alignment to sizeof(long) for struct rb_node.\n [RBTREE] Merge colour and parent fields of struct rb_node.\n [RBTREE] Remove dead code in rb_erase()\n [RBTREE] Update JFFS2 to use rb_parent() accessor macro.\n [RBTREE] Update eventpoll.c to use rb_parent() accessor macro.\n [RBTREE] Update key.c to use rb_parent() accessor macro.\n [RBTREE] Update ext3 to use rb_parent() accessor macro.\n [RBTREE] Change rbtree off-tree marking in I/O schedulers.\n [RBTREE] Add accessor macros for colour and parent fields of rb_node\n" }, { "commit": "6855a3a6c3ab611c3a393be846c1e36120033b18", "tree": "fc8b79da08a45dead0733ebe2e092ed39e30be01", "parents": [ "e6ed89ac9f5da16fea5111651b6de0ff0a76a5c2" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Tue May 30 21:25:31 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed May 31 16:27:10 2006 -0700" }, "message": "[PATCH] ext3 resize: fix double unlock_super()\n\nFrom: Andrew Morton \u003cakpm@osdl.org\u003e\n\nSpotted by Jan Capek \u003cjca@sysgo.com\u003e\n\nCc: \"Stephen C.

Issue summary:\n\n - FS codes have to process the entire string of options anyway.\n\n - Only FS codes that use quotas must have a show_options function (for\n quotas to work properly) however quotas are only used in a small number\n of FS.\n\n - Since most of the quota using FS support other options these FS codes\n should have the a show_options function to show those options - and the\n quota echoing becomes virtually negligible.\n\nBased on feedback I have modified my patches from the original:\n\n JFS a missing patch has been restored to the posting\n EXT[2|3] and JFS always use the show_options function\n - Each FS has at least one FS specific option displayed\n - QUOTA output is under a CONFIG_QUOTA ifdef\n - a follow-on patch will add a multitude of options for each FS\n EXT[2|3] and JFS \"quota\" is treated as \"usrquota\"\n EXT3 journalled data check for journalled quota removed\n EXT[2|3] mount when quota specified but not compiled in\n\n - no changes from my original patch. I tested the patch and the codes\n warn but\n\n - still mount. With all due respection I believe the comments\n otherwise were a\n\n - misread of the patch. Please reread/test and comment. XFS patch\n removed - the XFS team already made the necessary changes EXT3 mixing\n old and new quotas are handled differently (not purely exclusive)\n\n - if old and new quotas for the same type are used together the old\n type is silently depricated for compatability (e.g. usrquota and\n usrjquota)\n\n - mixing of old and new quotas is an error (e.g. usrjquota and\n grpquota)\n\nSigned-off-by: Mark Bellon \u003cmbellon@mvista.com\u003e\nAcked-by: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Jan Kara \u003cjack@ucw.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "cc314eef0128a807e50fa03baf2d0abc0647952c", "tree": "8e38db1be28006894915273b3f3cb3beaa6efda3", "parents": [ "2fb1e3086df9b454538491fba8121298da37cd23" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Aug 19 18:02:56 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Aug 19 18:02:56 2005 -0700" }, "message": "Fix nasty ncpfs symlink handling bug.\n\nThis bug could cause oopses and page state corruption, because ncpfs\nused the generic page-cache symlink handlign functions.
