When it\u0027s umounted and\ndestroys all the in-memory ecryptfs inodes, it fput\u0027s the lower_files and\nd_drop\u0027s the lower_dentries.

Hence in qa test 182,\nlog recovery only replayed a small handle for inode fsync\ntransactions in this case.\n\nHowever, with the removal of the extra -\u003esync_fs call, the log tail\nwas now not moved forward with the inode fsync transactions near the\nend of the sync procese the first (and only) buftarg flush occurred\nafter these transactions went to disk. The result is that log\nrecovery now sees a large number of transactions for metadata that\nis already on disk.\n\nThis usually isn\u0027t a problem, but when the transactions include\ninode chunk allocation, the inode create transactions and all\nsubsequent changes are replayed as we cannt rely on what is on disk\nis valid. As a result, if the inode was written and contains\nunlogged changes, the unlogged changes are lost, thereby violating\nsync semantics.\n\nThe fix is to always issue a transaction after the buftarg flush\noccurs is the log iѕ not idle or covered. This results in a dummy\ntransaction being written that contains the up-to-date log tail\nvalue, which will be very recent. Indeed, it will be at least as\nrecent as the old code would have left on disk, so log recovery\nwill behave exactly as it used to in this situation.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Alex Elder \u003caelder@sgi.com\u003e\n" }, { "commit": "c7f2e1f0ac142a657a1de00d404e1c8345b20598", "tree": "3afb52c22b24f2f31ec7c5638d87ab8bb1f04598", "parents": [ "2b0b39517d1af5294128dbc2fd7ed39c8effa540" ], "author": { "name": "Dmitry Monakhov", "email": "dmonakhov@openvz.org", "time": "Fri Apr 16 08:05:50 2010 -0500" }, "committer": { "name": "Dave Kleikamp", "email": "shaggy@linux.vnet.ibm.com", "time": "Fri Apr 16 08:05:50 2010 -0500" }, "message": "jfs: add jfs specific -\u003esetattr call\n\ngeneric setattr not longer responsible for quota transfer.\nuse jfs_setattr for all jfs\u0027s inodes.\n\nSigned-off-by: Dmitry Monakhov \u003cdmonakhov@openvz.org\u003e\nSigned-off-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\n" }, { "commit": "2b0b39517d1af5294128dbc2fd7ed39c8effa540", "tree": "f210f174aec2531294b6fbdb3890dffc709e32b9", "parents": [ "d7eecb483cc29e929bbc5515b8def830d7fc6ad2" ], "author": { "name": "Bill Pemberton", "email": "wfp5p@virginia.edu", "time": "Fri Apr 16 08:01:20 2010 -0500" }, "committer": { "name": "Dave Kleikamp", "email": "shaggy@linux.vnet.ibm.com", "time": "Fri Apr 16 08:01:20 2010 -0500" }, "message": "jfs: fix diAllocExt error in resizing filesystem\n\nResizing the filesystem would result in an diAllocExt error in some\ninstances because changes in bmp-\u003edb_agsize would not get noticed if\ngoto extendBmap was called.\n\nSigned-off-by: Bill Pemberton \u003cwfp5p@virginia.edu\u003e\nSigned-off-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\nCc: jfs-discussion@lists.sourceforge.net\nCc: linux-kernel@vger.kernel.org\n" }, { "commit": "1f1b0008e8dd1930d6e89522c70f4a438374302a", "tree": "fb35404bdb4db79925891779e3be118eca8e85dd", "parents": [ "ead88af5f577fd2b399a0fcdfe52605116fac489" ], "author": { "name": "Joern Engel", "email": "joern@logfs.org", "time": "Thu Apr 15 08:03:57 2010 +0200" }, "committer": { "name": "Joern Engel", "email": "joern@logfs.org", "time": "Thu Apr 15 08:03:57 2010 +0200" }, "message": "[LogFS] Prevent mempool_destroy NULL pointer dereference\n\nIt would probably be better to just accept NULL pointers in\nmempool_destroy().
