This delayed the hashing of lookup dentrys until the -\u003emkdir()\n(or -\u003esymlink()) operation completed to ensure we always went through\n-\u003elookup() instead of also having processes go through -\u003erevalidate() so\nour VFS locking remained consistent.\n\nNow we are seeing a couple of side affects of that change in situations\nwith heavy mount activity.\n\nTwo cases have been identified:\n\n1) When a mount request is triggered, due to the delayed hashing, the\n directory created by user space for the mount point doesn\u0027t have the\n DCACHE_AUTOFS_PENDING flag set. In the case of an autofs multi-mount\n where a tree of mount point directories are created this can lead to\n the path walk continuing rather than the dentry being sent to the wait\n queue to wait for request completion. This is because, if the pending\n flag isn\u0027t set, the criteria for deciding this is a mount in progress\n fails to hold, namely that the dentry is not a mount point and has no\n subdirectories.\n\n2) A mount request dentry is initially created negative and unhashed.\n It remains this way until the -\u003emkdir() callback completes. Since it\n is unhashed a fresh dentry is used when the user space mount request\n creates the mount point directory. This leaves the original dentry\n negative and unhashed. But revalidate has no way to tell the VFS that\n the dentry has changed, other than to force another -\u003elookup() by\n returning false, which is at best wastefull and at worst not possible.\n This results in an -ENOENT return from the original path walk when in\n fact the mount succeeded.\n\nTo resolve this we need to ensure that the same dentry is used in all\ncalls to -\u003elookup() during the course of a mount request. This patch\nachieves that by adding the initial dentry to a look aside list and\nremoves it at -\u003emkdir() or -\u003esymlink() completion (or when the dentry is\nreleased), since these are the only create operations autofs4 supports.\n\nSigned-off-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "caf7da3d5d4d9dd873eb52d025d8cc63b89f1fdb", "tree": "9e53359c28c4247eae9685a5f9c63a5c0a54a7b1", "parents": [ "5f6f4f28b6ba543beef8bad91aa6f69c7ffeee51" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Jul 23 21:30:11 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:31 2008 -0700" }, "message": "autofs4: revert - redo lookup in ttfd\n\nThis patch series enables the use of a single dentry for lookups prior to\nthe dentry being hashed and so we no longer need to redo the lookup.

Since the VFS can\u0027t find an entry\nfor \"foo\" under /mount/submount, it calls into the autofs4 kernel module to\nallocate a new dentry, D1. The kernel creates a new waitq for this lookup and\ncalls the daemon to perform the mount.\n\nThe daemon performs a mkdir of the \"foo\" directory under /mount/submount,\nwhich ends up creating a *new* dentry, D2.\n\nThen, P2 does a lookup of /mount/submount/foo. The VFS path walking logic\nfinds a dentry in the dcache, D2, and calls the revalidate function with this.\n In the autofs4 revalidate code, we then trigger a mount, since the dentry is\nan empty directory that isn\u0027t a mountpoint, and so set DCACHE_AUTOFS_PENDING\nand call into the wait code to trigger the mount.\n\nThe wait code finds our existing waitq entry (since it is keyed off of the\ndirectory name) and adds itself to the list of waiters.\n\nAfter the daemon finishes the mount, it calls back into the kernel to release\nthe waiters. When this happens, P1 is woken up and goes about clearing the\nDCACHE_AUTOFS_PENDING flag, but it does this in D1! So, given that P1 in our\ncase is a program that will immediately try to access a file under\n/mount/submount/foo, we end up finding the dentry D2 which still has the\npending flag set, and we set out to wait for a mount *again*!\n\nSo, one way to address this is to re-do the lookup at the end of\ntry_to_fill_dentry, and to clear the pending flag on the hashed dentry. This\nseems a sane approach to me.\"\n\nAnd Jeff\u0027s patch does this.\n\nSigned-off-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f249fdd8c19ff65825c0be67212cdf22e556668e", "tree": "d8eb3c461ef5ba0f6692e237548c755f47bbf8b4", "parents": [ "58b250daff6a24518813975143c8433d9d5b684f" ], "author": { "name": "Harvey Harrison", "email": "harvey.harrison@gmail.com", "time": "Tue Apr 29 00:59:03 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Apr 29 08:06:01 2008 -0700" }, "message": "autofs4: fix sparse warning in root.c\n\nfs/autofs4/root.c:536:23: warning: symbol \u0027ino\u0027 shadows an earlier one\nfs/autofs4/root.c:510:22: originally declared here\n\nThere is no need to redeclare, we are at the end of the loop and in\nthe next iteration of the loop, ino will be reset.\n\nSigned-off-by: Harvey Harrison \u003charvey.harrison@gmail.com\u003e\nAcked-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1d957f9bf87da74f420424d16ece005202bbebd3", "tree": "363d4770c0c74a536524c99ccd2762ce96ee9bbe", "parents": [ "4ac9137858e08a19f29feac4e1f4df7c268b0ba5" ], "author": { "name": "Jan Blunck", "email": "jblunck@suse.de", "time": "Thu Feb 14 19:34:35 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Feb 14 21:13:33 2008 -0800" }, "message": "Introduce path_put()\n\n* Add path_put() functions for releasing a reference to the dentry and\n vfsmount of a struct path in the right order\n\n* Switch from path_release(nd) to path_put(\u0026nd-\u003epath)\n\n* Rename dput_path() to path_put_conditional()\n\n[akpm@linux-foundation.org: fix cifs]\nSigned-off-by: Jan Blunck \u003cjblunck@suse.de\u003e\nSigned-off-by: Andreas Gruenbacher \u003cagruen@suse.de\u003e\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: \u003clinux-fsdevel@vger.kernel.org\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Steven French \u003csfrench@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4ac9137858e08a19f29feac4e1f4df7c268b0ba5", "tree": "f5b5d84fd12fcc2b0ba0e7ce1a79ff381ad8f5dd", "parents": [ "c5e725f33b733a77de622e91b6ba5645fcf070be" ], "author": { "name": "Jan Blunck", "email": "jblunck@suse.de", "time": "Thu Feb 14 19:34:32 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Feb 14 21:13:33 2008 -0800" }, "message": "Embed a struct path into struct nameidata instead of nd-\u003e{dentry,mnt}\n\nThis is the central patch of a cleanup series.

In this case, since the the lookup gets a new\ndentry, it doesn\u0027t know that there is an expire in progress and when it posts\nits mount request, matches the existing expire request and waits for its\ncompletion. ENOENT is then returned to user space from lookup (as the dentry\npassed in is now unhashed) without having performed the mount request.\n\nThe solution used here is to keep track of dentrys in this unhashed state and\nreuse them, if possible, in order to preserve the flags. Additionally, this\ninfrastructure will provide the framework for the reintroduction of caching of\nmount fails removed earlier in development.\n\nSigned-off-by: Ian Kent \u003craven@themaw.net\u003e\nAcked-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "754661f143e70d66eae6c48532ca245aa05dec0e", "tree": "c3ed0f7f96061931e497ed92d2b21294756b4831", "parents": [ "9c2e08c592cd357a8330c34def1e8ecfdcf53275" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Mon Feb 12 00:55:38 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Feb 12 09:48:46 2007 -0800" }, "message": "[PATCH] mark struct inode_operations const 1\n\nMany struct inode_operations in the kernel can be \"const\".
