So the solution is to add a new mount option (subvolrootid)\nto specify subvol id of root and search subvol name in it. For\nour case, now we can use \"-o subvolrootid\u003d0,subvol\u003dmeego_home)\nto mount meego_home.\n\nDetail information can be found in meego bugzilla:\nhttps://bugs.meego.com/show_bug.cgi?id\u003d15055\n\nSigned-off-by: Zhong, Xin \u003cxin.zhong@intel.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "13f2696f1da9700d401db0ac2bc27ebc17068b22", "tree": "fa7e518f896ed8f69da76b0feb33867a73aa2cce", "parents": [ "a1b75f7d961955e697ec377f90115e3517df98f9" ], "author": { "name": "Daniel J Blueman", "email": "daniel.blueman@gmail.com", "time": "Mon Apr 11 15:56:31 2011 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Mon Apr 11 20:25:46 2011 -0400" }, "message": "fix user annotation in ioctl.c\n\nFix address space annotation correct in ioctl.c.\n\nSigned-off-by: Daniel J Blueman \u003cdaniel.blueman@gmail.com\u003e\n\n \t\t BTRFS_BLOCK_GROUP_SYSTEM,\n@@ -2387,7 +2387,7 @@ long btrfs_ioctl_space_info(struct btrfs_root\n*root, void __user *arg)\n \t\tup_read(\u0026info-\u003egroups_sem);\n \t}\n\n-\tuser_dest \u003d (struct btrfs_ioctl_space_info *)\n+\tuser_dest \u003d (struct btrfs_ioctl_space_info __user *)\n \t\t(arg + sizeof(struct btrfs_ioctl_space_args));\n\n \tif (copy_to_user(user_dest, dest_orig, alloc_size))\nReviewed-by: Josef Bacik \u003cjosef@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "a1b75f7d961955e697ec377f90115e3517df98f9", "tree": "ae7fe104dc20222f05be528d85f3c4fa40aa9331", "parents": [ "3387206f26e1b48703e810175b98611a4fd8e8ea" ], "author": { "name": "Josef Bacik", "email": "josef@redhat.com", "time": "Fri Apr 08 15:51:18 2011 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Mon Apr 11 20:25:06 2011 -0400" }, "message": "Btrfs: check for duplicate iov_base\u0027s when doing dio reads\n\nApparently it is ok to submit a read to an IDE device with the same target page\nfor different offsets.

However, we can have thousands of delalloc\nextents, resulting in an allocation size orders of magnitude larger\nthan is needed to hold all the real extents.\n\nFix this by limiting the size of the buffer being allocated to the\nsize of the literal area of the inodes in the filesystem (i.e. the\nmaximum size an inode fork can grow to).\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Alex Elder \u003caelder@sgi.com\u003e\n" }, { "commit": "37adb89fadd65ce47f7e5cfd564938a76b351948", "tree": "b935bde3f61965a8e0810f9d12281b97b2376351", "parents": [ "418875900e3de4831c84f86ae4756690dac5be77" ], "author": { "name": "Bryan Schumaker", "email": "bjschuma@netapp.com", "time": "Thu Apr 07 16:02:20 2011 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Thu Apr 07 13:19:40 2011 -0700" }, "message": "NFS: Change initial mount authflavor only when server returns NFS4ERR_WRONGSEC\n\nWhen attempting an initial mount, we should only attempt other\nauthflavors if AUTH_UNIX receives a NFS4ERR_WRONGSEC error.\nThis allows other errors to be passed back to userspace programs.\n\nSigned-off-by: Bryan Schumaker \u003cbjschuma@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "ccfeef0ff76ebd632ae51bc56700f0072c4f1864", "tree": "83ec5932dac631a455a69212b505f68f57f68cdf", "parents": [ "42933bac11e811f02200c944d8562a15f8ec4ff0", "6bef0b67474d71e0d6484cbabcc87657a1176d8d" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 07 11:31:03 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 07 11:31:03 2011 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.infradead.org/ubifs-2.6\n\n* \u0027for-linus\u0027 of git://git.infradead.org/ubifs-2.6:\n UBI: do not select KALLSYMS_ALL\n UBI: do not compare array with NULL\n UBI: check if we are in RO mode in the erase routine\n UBIFS: fix debugging failure in dbg_check_space_info\n UBIFS: fix error path in dbg_debugfs_init_fs\n UBIFS: unify error path dbg_debugfs_init_fs\n UBIFS: do not select KALLSYMS_ALL\n UBIFS: fix assertion warnings\n UBIFS: fix oops on error path in read_pnode\n UBIFS: do not read flash unnecessarily\n" }, { "commit": "42933bac11e811f02200c944d8562a15f8ec4ff0", "tree": "fcdd9afe56eb0e746565ddd1f92f22d36678b843", "parents": [ "2b9accbee563f535046ff2cd382d0acaa92e130c", "25985edcedea6396277003854657b5f3cb31a628" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 07 11:14:49 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 07 11:14:49 2011 -0700" }, "message": "Merge branch \u0027for-linus2\u0027 of git://git.profusion.mobi/users/lucas/linux-2.6\n\n* \u0027for-linus2\u0027 of git://git.profusion.mobi/users/lucas/linux-2.6:\n Fix common misspellings\n" }, { "commit": "418875900e3de4831c84f86ae4756690dac5be77", "tree": "d0609f12b62962806adc092867350b7bfcfed5a3", "parents": [ "0867659fa3c245bf203d837a82e0f6ea5079c2c5" ], "author": { "name": "Bryan Schumaker", "email": "bjschuma@netapp.com", "time": "Wed Apr 06 14:33:28 2011 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Apr 06 13:25:04 2011 -0700" }, "message": "NFS: Fix a signed vs. unsigned secinfo bug\n\nrpc_authflavor_t is cast from an unsigned int, but the\ninitial code tried to use it as a signed int.

The easiest way to go is to forget\nabout KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is\nenabled - that should be enough for stackdumps.\n\nReported-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\nAcked-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\n" }, { "commit": "c88ac00c5af70c2a0741da14b22cdcf8507ddd92", "tree": "5561ff6e47406f58e71eda4700c5a3f2694c6f71", "parents": [ "54acbaaa523ca0bd284a18f67ad213c379679e86" ], "author": { "name": "Artem Bityutskiy", "email": "Artem.Bityutskiy@nokia.com", "time": "Tue Mar 29 09:45:21 2011 +0300" }, "committer": { "name": "Artem Bityutskiy", "email": "Artem.Bityutskiy@nokia.com", "time": "Tue Apr 05 10:45:09 2011 +0300" }, "message": "UBIFS: fix assertion warnings\n\nThis patch fixes UBIFS assertion warnings like:\n\nUBIFS assert failed in ubifs_leb_unmap at 135 (pid 29365)\nPid: 29365, comm: integck Tainted: G I 2.6.37-ubi-2.6+ #34\nCall Trace:\n [\u003cffffffffa047c663\u003e] ubifs_lpt_init+0x95e/0x9ee [ubifs]\n [\u003cffffffffa04623a7\u003e] ubifs_remount_fs+0x2c7/0x762 [ubifs]\n [\u003cffffffff810f066e\u003e] do_remount_sb+0xb6/0x101\n [\u003cffffffff81106ff4\u003e] ? do_mount+0x191/0x78e\n [\u003cffffffff811070bb\u003e] do_mount+0x258/0x78e\n [\u003cffffffff810da1e8\u003e] ? alloc_pages_current+0xa2/0xc5\n [\u003cffffffff81107674\u003e] sys_mount+0x83/0xbd\n [\u003cffffffff81009a12\u003e] system_call_fastpath+0x16/0x1b\n\nThey happen when we re-mount from R/O mode to R/W mode.
