There have been multiple reports on\ndifferent kernel versions pointing to this common issue:\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d12557\nhttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/269954\nhttp://bugs.debian.org/cgi-bin/bugreport.cgi?bug\u003d508866.html\n\nThis issue can be reproducible consistently by doing this on a NFS mounted\nhome (KDE):\n1. Open 2 xterm sessions\n2. From one of the xterm session, do \"ssh -X \u003cremote host\u003e\"\n3. \"stat ~/.Xauthority\" on the remote SSH session\n4. Close the two xterm sessions\n5. On the server do a \"stat ~/.Xauthority\"\n6. Now on the client, try to open xterm\nThis will fail.\n\nEven if the filehandle had become stale, the NFS client should invalidate\nthe cache/inode and should repeat LOOKUP. Looking at the packet capture when\nthe failure occurs shows that there were two subsequent ACCESS() calls with\nthe same filehandle and both fails with -ESTALE error.\n\nI have tested the fix below. Now the client issue a LOOKUP after the\nACCESS() call fails with -ESTALE. If all this makes sense to you, can you\nconsider this for inclusion?\n\nThanks,\n\n\nIf the server returns an -ESTALE error due to stale filehandle in response to\nan ACCESS() call, we need to invalidate the cache and inode so that LOOKUP()\ncan be retried.

VM_NORESERVE may\nbe set because an application can request no reserves be made for hugetlbfs\nat the risk of getting killed later.\n\nWith commit fc8744adc870a8d4366908221508bb113d8b72ee, VM_NORESERVE and\nVM_ACCOUNT are getting unconditionally set for hugetlbfs-backed mappings. This\nbreaks the accounting for both the core VM and hugetlbfs, can trigger an\nOOM storm when hugepage pools are too small lockups and corrupted counters\notherwise are used. This patch brings hugetlbfs more in line with how the\ncore VM treats VM_NORESERVE but prevents VM_ACCOUNT being set.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ba4439165f0f0d25b2fe065cf0c1ff8130b802eb", "tree": "242f9aa5cc4fe0ca7d3062aa0a7ec713a4346bb8", "parents": [ "7be2baaa0322c59ba888aa5260a8c130666acd41" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Tue Feb 10 11:14:34 2009 -0500" }, "committer": { "name": "Theodore Tso", "email": "tytso@mit.edu", "time": "Tue Feb 10 11:14:34 2009 -0500" }, "message": "ext4: Fix lockdep warning\n\nWe should not call ext4_mb_add_n_trim while holding alloc_semp.\n\n \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n [ INFO: possible recursive locking detected ]\n 2.6.29-rc4-git1-dirty #124\n ---------------------------------------------\n ffsb/3116 is trying to acquire lock:\n (\u0026meta_group_info[i]-\u003ealloc_sem){----}, at: [\u003cffffffff8035a6e8\u003e]\n ext4_mb_load_buddy+0xd2/0x343\n\n but task is already holding lock:\n (\u0026meta_group_info[i]-\u003ealloc_sem){----}, at: [\u003cffffffff8035a6e8\u003e]\n ext4_mb_load_buddy+0xd2/0x343\n\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d12672\n\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "7be2baaa0322c59ba888aa5260a8c130666acd41", "tree": "a1543a38923d60092e06741ab3dee9ce9af32abc", "parents": [ "7f5aa215088b817add9c71914b83650bdd49f8a9" ], "author": { "name": "Wei Yongjun", "email": "yjwei@cn.fujitsu.com", "time": "Tue Feb 10 09:53:42 2009 -0500" }, "committer": { "name": "Theodore Tso", "email": "tytso@mit.edu", "time": "Tue Feb 10 09:53:42 2009 -0500" }, "message": "ext4: Fix to read empty directory blocks correctly in 64k\n\nThe rec_len field in the directory entry is 16 bits, so there was a\nproblem representing rec_len for filesystems with a 64k block size in\nthe case where the directory entry takes the entire 64k block.\nUnfortunately, there were two schemes that were proposed; one where\nall zeros meant 65536 and one where all ones (65535) meant 65536.\nE2fsprogs used 0, whereas the kernel used 65535.
