For\n same inode X, the ntfs_inode is dirty and thus corresponding on-disk\n inode, i.e. mft record, which is in a dirty PAGE_CACHE_PAGE belonging\n to the table of inodes, i.e. $MFT, inode 0.\n What happens:\n Process 1: sys_sync()/umount()/whatever... calls\n __sync_single_inode() for $MFT -\u003e do_writepages() -\u003e write_page for\n the dirty page containing the on-disk inode X, the page is now locked\n -\u003e ntfs_write_mst_block() which clears PageUptodate() on the page to\n prevent anyone else getting hold of it whilst it does the write out.\n This is necessary as the on-disk inode needs \"fixups\" applied before\n the write to disk which are removed again after the write and\n PageUptodate is then set again. It then analyses the page looking\n for dirty on-disk inodes and when it finds one it calls\n ntfs_may_write_mft_record() to see if it is safe to write this\n on-disk inode. This then calls ilookup5() to check if the\n corresponding VFS inode is in icache(). This in turn calls ifind()\n which waits on the inode lock via wait_on_inode whilst holding the\n global inode_lock.\n Process 2: pdflush results in a call to __sync_single_inode for the\n same VFS inode X on the ntfs volume. This locks the inode (I_LOCK)\n then calls write-inode -\u003e ntfs_write_inode -\u003e map_mft_record() -\u003e\n read_cache_page() for the page (in page cache of table of inodes\n $MFT, inode 0) containing the on-disk inode. This page has\n PageUptodate() clear because of Process 1 (see above) so\n read_cache_page() blocks when it tries to take the page lock for the\n page so it can call ntfs_read_page().\n Thus Process 1 is holding the page lock on the page containing the\n on-disk inode X and it is waiting on the inode X to be unlocked in\n ifind() so it can write the page out and then unlock the page.\n And Process 2 is holding the inode lock on inode X and is waiting for\n the page to be unlocked so it can call ntfs_readpage() or discover\n that Process 1 set PageUptodate() again and use the page.\n Thus we have a deadlock due to ifind() waiting on the inode lock.\n The solution: The fix is to use the newly introduced\n ilookup5_nowait() which does not wait on the inode\u0027s lock and hence\n avoids the deadlock. This is safe as we do not care about the VFS\n inode and only use the fact that it is in the VFS inode cache and the\n fact that the vfs and ntfs inodes are one struct in memory to find\n the ntfs inode in memory if present. Also, the ntfs inode has its\n own locking so it does not matter if the vfs inode is locked.\n\nSigned-off-by: Anton Altaparmakov \u003caia21@cantab.net\u003e\n" }, { "commit": "fa3be92317c4ae34edcf5274e8bbeff181e20b7a", "tree": "84ae4ace6c891aa95b804950283e1f8f3e46c730", "parents": [ "1d58b27b8d77ecb816cfa8f846b78c845675eb89" ], "author": { "name": "Anton Altaparmakov", "email": "aia21@cantab.net", "time": "Sat Jun 25 17:15:36 2005 +0100" }, "committer": { "name": "Anton Altaparmakov", "email": "aia21@cantab.net", "time": "Sat Jun 25 17:15:36 2005 +0100" }, "message": "NTFS: Add an extra parameter @last_vcn to ntfs_get_size_for_mapping_pairs()\n and ntfs_mapping_pairs_build() to allow the runlist encoding to be\n partial which is desirable when filling holes in sparse attributes.\n Update all callers.\n\nSigned-off-by: Anton Altaparmakov \u003caia21@cantab.net\u003e\n" }, { "commit": "c0c1cc0e46b36347f11b566f99087dc5e6fc1b89", "tree": "773105bdde7454d10dccc127048a9847f7e01f11", "parents": [ "271849a98849394ea85fa7caa8a1aaa2b3a849b7" ], "author": { "name": "Anton Altaparmakov", "email": "aia21@cantab.net", "time": "Mon Mar 07 21:43:38 2005 +0000" }, "committer": { "name": "Anton Altaparmakov", "email": "aia21@cantab.net", "time": "Thu May 05 11:20:49 2005 +0100" }, "message": "NTFS: - Fix bug in fs/ntfs/attrib.c::ntfs_find_vcn_nolock() where after\n dropping the read lock and taking the write lock we were not checking\n whether someone else did not already do the work we wanted to do.\n - Rename ntfs_find_vcn_nolock() to ntfs_attr_find_vcn_nolock().\n - Tidy up some comments in fs/ntfs/runlist.c.\n - Add LCN_ENOMEM and LCN_EIO definitions to fs/ntfs/runlist.h.\n\nSigned-off-by: Anton Altaparmakov \u003caia21@cantab.net\u003e\n" }, { "commit": "8907547d4b099e67762ea4891c127ea1f6dd1cb7", "tree": "74fa9c887db8a7915325ad9a76d874ed134c0d9a", "parents": [ "5ae9fcf8f329baba4bada8719cb0337eef083a1a" ], "author": { "name": "Randy Dunlap", "email": "rddunlap@osdl.org", "time": "Thu Mar 03 11:19:53 2005 +0000" }, "committer": { "name": "Anton Altaparmakov", "email": "aia21@cantab.net", "time": "Thu May 05 11:11:47 2005 +0100" }, "message": "NTFS: Fix printk format warnings on ia64.
