Immediately one things of just adding the ability to remount\nautofs file systems would solve it, but alas, that can\u0027t work. This is\nbecause autofs direct mounts and the implementation of \"on demand mount\nand expire\" of nested mount trees have the file system mounted on top of\nthe mount trigger dentry.\n\nTo resolve this a miscellaneous device node for routing ioctl commands to\nthese mount points has been implemented in the autofs4 kernel module and a\nlibrary added to autofs. This provides the ability to open a file\ndescriptor for these over mounted autofs mount points.\n\nPlease refer to Documentation/filesystems/autofs4-mount-control.txt for a\ndiscussion of the problem, implementation alternatives considered and a\ndescription of the interface.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: build fix]\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": "c0f54d3e54fd7ac6723b2125d881f1b25d21ed16", "tree": "3215eeae82b4c81094227b78ad668943c69b46e5", "parents": [ "bb979d7fc360bc37cbaff43a6fafceb897cb5e47" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Oct 15 22:02:52 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 16 11:21:39 2008 -0700" }, "message": "autofs4: track uid and gid of last mount requester\n\nTrack the uid and gid of the last process to request a mount for on an\nautofs dentry.\n\n[akpm@linux-foundation.org: fix tpyo in comment]\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": "bb979d7fc360bc37cbaff43a6fafceb897cb5e47", "tree": "b99f90b4cacebf1e8cd5725917fd14cf8d1c50ac", "parents": [ "624ae5284516870657505103ada531c64dba2a9a" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Oct 15 22:02:52 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 16 11:21:39 2008 -0700" }, "message": "autofs4: cleanup autofs mount type usage\n\nUsage of the AUTOFS_TYPE_* defines is a little confusing and appears\ninconsistent.\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": "624ae5284516870657505103ada531c64dba2a9a", "tree": "1098d75abc1f4d335e2276dd9dde00a60ee568b5", "parents": [ "807b7ebe41ab80d96e89a53bc290d49613e56f48" ], "author": { "name": "Tyler Hicks", "email": "tyhicks@linux.vnet.ibm.com", "time": "Wed Oct 15 22:02:51 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 16 11:21:39 2008 -0700" }, "message": "eCryptfs: remove netlink transport\n\nThe netlink transport code has not worked for a while and the miscdev\ntransport is a simpler solution.

I only had to\nmake small modifications to it.\n\nFirst, because the bucket size is 4K, a new field named xh_free_start is added\nin ocfs2_xattr_header to indicate the next valid name/value offset in a bucket.\nIt is used when we store new EA name/value. With this field, we can find the\nplace more quickly and what\u0027s more, we don\u0027t need to sort the name/value every\ntime to let the last entry indicate the next unused space. This makes the\ninsert operation more efficient for blocksizes smaller than 4k.\n\nBecause of the new xh_free_start, another field named as xh_name_value_len is\nalso added in ocfs2_xattr_header. It records the total length of all the\nname/values in the bucket. We need this so that we can check it and defragment\nthe bucket if there is not enough contiguous free space.\n\nAn xattr insertion looks like this:\n1. xattr_index_block_find: find the right bucket by the name_hash, say bucketA.\n2. check whether there is enough space in bucketA. If yes, insert it directly\n and modify xh_free_start and xh_name_value_len accordingly. If not, check\n xh_name_value_len to see whether we can store this by defragment the bucket.\n If yes, defragment it and go on insertion.\n3. If defragement doesn\u0027t work, check whether there is new empty bucket in\n the clusters within this extent record. If yes, init the new bucket and move\n all the buckets after bucketA one by one to the next bucket. Move half of the\n entries in bucketA to the next bucket and go on insertion.\n4. If there is no new bucket, grow the extent tree.\n\nAs for xattr deletion, we will delete an xattr bucket when all it\u0027s xattrs\nare removed and move all the buckets after it to the previous one. When all\nthe xattr buckets in an extend record are freed, free this extend records\nfrom ocfs2_xattr_tree.\n\nSigned-off-by: Tao Ma \u003ctao.ma@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "ca12b7c48942d21b2e7890b820db9d578bc291cd", "tree": "e051e6ceb77a05db7dd1d749d7f3f1682c69196c", "parents": [ "589dc2602f2a1b7fa5e59b90f548af189f128d77" ], "author": { "name": "Tao Ma", "email": "tao.ma@oracle.com", "time": "Mon Aug 18 17:38:52 2008 +0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Mon Oct 13 16:57:03 2008 -0700" }, "message": "ocfs2: Optionally limit extent size in ocfs2_insert_extent()\n\nIn xattr bucket, we want to limit the maximum size of a btree leaf,\notherwise we\u0027ll lose the benefits of hashing because we\u0027ll have to search\nlarge leaves.\n\nSo add a new field in ocfs2_extent_tree which indicates the maximum leaf cluster\nsize we want so that we can prevent ocfs2_insert_extent() from merging the leaf\nrecord even if it is contiguous with an adjacent record.\n\nOther btree types are not affected by this change.\n\nSigned-off-by: Tao Ma \u003ctao.ma@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "589dc2602f2a1b7fa5e59b90f548af189f128d77", "tree": "0a87e16146aa06c72de8db0aed1215c8be72b5fc", "parents": [ "0c044f0b24b9128ba8c297149d88bd81f2e36af3" ], "author": { "name": "Tao Ma", "email": "tao.ma@oracle.com", "time": "Mon Aug 18 17:38:51 2008 +0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Mon Oct 13 16:57:03 2008 -0700" }, "message": "ocfs2: Add xattr lookup code xattr btrees\n\nAdd code to lookup a given extended attribute in the xattr btree.
