The C standard says \"If one operand has\nunsigned int type, the other operand is converted to unsigned int\", so\nthe compiler is not to blame. As a result, DIV_ROUND_CLOSEST(0, 2U) and\nsimilar operations now return bad values, since the automatic conversion\nof expressions such as \"0 - 2U/2\" to unsigned was not taken into\naccount.\n\nFix by checking for the divisor variable type when deciding which\noperation to perform. This fixes DIV_ROUND_CLOSEST(0, 2U), but still\nreturns bad values for negative dividends divided by unsigned divisors.\nMark the latter case as unsupported.\n\nOne observed effect of this problem is that the s2c_hwmon driver reports\na value of 4198403 instead of 0 if the ADC reads 0.\n\nOther impact is unpredictable.

The final call to fscache_put_operation() can then check that an op\n in the appropriate state (complete or cancelled).\n\n (3) Adjust the use of object-\u003en_ops, -\u003en_in_progress, -\u003en_exclusive to better\n govern the state of an object:\n\n\t(a) The -\u003en_ops is now the number of extant operations on the object\n\t and is now decremented by fscache_put_operation() only.\n\n\t(b) The -\u003en_in_progress is simply the number of objects that have been\n\t taken off of the object\u0027s pending queue for the purposes of being\n\t run. This is decremented by fscache_op_complete() only.\n\n\t(c) The -\u003en_exclusive is the number of exclusive ops that have been\n\t submitted and queued or are in progress. It is decremented by\n\t fscache_op_complete() and by fscache_cancel_op().\n\n fscache_put_operation() and fscache_operation_gc() now no longer try to\n clean up -\u003en_exclusive and -\u003en_in_progress.

Furthermore, if an object is active and there are\n runnable ops against it, there must be at least one op running.\n\n (4) Add a remaining-pages counter (n_pages) to struct fscache_retrieval and\n provide a function to record completion of the pages as they complete.\n\n When n_pages reaches 0, the operation is deemed to be complete and\n fscache_op_complete() is called.\n\n Add calls to fscache_retrieval_complete() anywhere we\u0027ve finished with a\n page we\u0027ve been given to read or allocate for. This includes places where\n we just return pages to the netfs for reading from the server and where\n accessing the cache fails and we discard the proposed netfs page.\n\nThe bugs in the unfixed state management manifest themselves as oopses like the\nfollowing where the operation completion gets out of sync with return of the\ncookie by the netfs. This is possible because the cache unlocks and returns\nall the netfs pages before recording its completion - which means that there\u0027s\nnothing to stop the netfs discarding them and returning the cookie.\n\n\nFS-Cache: Cookie \u0027NFS.fh\u0027 still has outstanding reads\n------------[ cut here ]------------\nkernel BUG at fs/fscache/cookie.c:519!\ninvalid opcode: 0000 [#1] SMP\nCPU 1\nModules linked in: cachefiles nfs fscache auth_rpcgss nfs_acl lockd sunrpc\n\nPid: 400, comm: kswapd0 Not tainted 3.1.0-rc7-fsdevel+ #1090 /DG965RY\nRIP: 0010:[\u003cffffffffa007050a\u003e] [\u003cffffffffa007050a\u003e] __fscache_relinquish_cookie+0x170/0x343 [fscache]\nRSP: 0018:ffff8800368cfb00 EFLAGS: 00010282\nRAX: 000000000000003c RBX: ffff880023cc8790 RCX: 0000000000000000\nRDX: 0000000000002f2e RSI: 0000000000000001 RDI: ffffffff813ab86c\nRBP: ffff8800368cfb50 R08: 0000000000000002 R09: 0000000000000000\nR10: ffff88003a1b7890 R11: ffff88001df6e488 R12: ffff880023d8ed98\nR13: ffff880023cc8798 R14: 0000000000000004 R15: ffff88003b8bf370\nFS: 0000000000000000(0000) GS:ffff88003bd00000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b\nCR2: 00000000008ba008 CR3: 0000000023d93000 CR4: 00000000000006e0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400\nProcess kswapd0 (pid: 400, threadinfo ffff8800368ce000, task ffff88003b8bf040)\nStack:\n ffff88003b8bf040 ffff88001df6e528 ffff88001df6e528 ffffffffa00b46b0\n ffff88003b8bf040 ffff88001df6e488 ffff88001df6e620 ffffffffa00b46b0\n ffff88001ebd04c8 0000000000000004 ffff8800368cfb70 ffffffffa00b2c91\nCall Trace:\n [\u003cffffffffa00b2c91\u003e] nfs_fscache_release_inode_cookie+0x3b/0x47 [nfs]\n [\u003cffffffffa008f25f\u003e] nfs_clear_inode+0x3c/0x41 [nfs]\n [\u003cffffffffa0090df1\u003e] nfs4_evict_inode+0x2f/0x33 [nfs]\n [\u003cffffffff810d8d47\u003e] evict+0xa1/0x15c\n [\u003cffffffff810d8e2e\u003e] dispose_list+0x2c/0x38\n [\u003cffffffff810d9ebd\u003e] prune_icache_sb+0x28c/0x29b\n [\u003cffffffff810c56b7\u003e] prune_super+0xd5/0x140\n [\u003cffffffff8109b615\u003e] shrink_slab+0x102/0x1ab\n [\u003cffffffff8109d690\u003e] balance_pgdat+0x2f2/0x595\n [\u003cffffffff8103e009\u003e] ? process_timeout+0xb/0xb\n [\u003cffffffff8109dba3\u003e] kswapd+0x270/0x289\n [\u003cffffffff8104c5ea\u003e] ? __init_waitqueue_head+0x46/0x46\n [\u003cffffffff8109d933\u003e] ? balance_pgdat+0x595/0x595\n [\u003cffffffff8104bf7a\u003e] kthread+0x7f/0x87\n [\u003cffffffff813ad6b4\u003e] kernel_thread_helper+0x4/0x10\n [\u003cffffffff81026b98\u003e] ? finish_task_switch+0x45/0xc0\n [\u003cffffffff813abcdd\u003e] ? retint_restore_args+0xe/0xe\n [\u003cffffffff8104befb\u003e] ? __init_kthread_worker+0x53/0x53\n [\u003cffffffff813ad6b0\u003e] ? gs_change+0xb/0xb\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "ef46ed888efb1e8da33be5d33c9b54476289a43b", "tree": "d538dc01a075162f95da416da1fb5d6fd676445a", "parents": [ "37491a1339df26259b06dfa33f30e574e9e52034" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Dec 20 21:52:35 2012 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Dec 20 21:58:25 2012 +0000" }, "message": "FS-Cache: Make cookie relinquishment wait for outstanding reads\n\nMake fscache_relinquish_cookie() log a warning and wait if there are any\noutstanding reads left on the cookie it was given.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "a13eea6bd9ee62ceacfc5243d54c84396bc86cb4", "tree": "46192468880c144f2b367deb5188267866ee1fac", "parents": [ "fcc16882ac4532aaa644bff444f0c5d6228ba71e", "6666e6aa9f36b2bfd6b30072c07b34f2a24becf1" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 20 13:54:51 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 20 13:54:52 2012 -0800" }, "message": "Merge tag \u0027for-3.8-merge\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs\n\nPull new F2FS filesystem from Jaegeuk Kim:\n \"Introduce a new file system, Flash-Friendly File System (F2FS), to\n Linux 3.8.\n\n Highlights:\n - Add initial f2fs source codes\n - Fix an endian conversion bug\n - Fix build failures on random configs\n - Fix the power-off-recovery routine\n - Minor cleanup, coding style, and typos patches\"\n\nFrom the Kconfig help text:\n\n F2FS is based on Log-structured File System (LFS), which supports\n versatile \"flash-friendly\" features.

result in a wrong value if the modulus wasn\u0027t a power-of-two.\n\nSo re-write the code to not only protect against the divide-by-zero, but\nto do the starting sector arithmetic in sectors, and

Not only this can help to find the potential\nproblems, we do not want the false warnings if, say, the task takes two\ndifferent percpu_rw_semaphore\u0027s for reading. IOW, at least -\u003erw_sem\nshould not use a single class.\n\nThis patch exposes this internal lock to lockdep so that it represents the\nwhole percpu_rw_semaphore. This way we do not need to add another \"fake\"\n-\u003elockdep_map and lock_class_key. More importantly, this also makes the\noutput from lockdep much more understandable if it finds the problem.\n\nIn short, with this patch from lockdep pov percpu_down_read() and\npercpu_up_read() acquire/release -\u003erw_sem for reading, this matches the\nactual semantics. This abuses __up_read() but I hope this is fine and in\nfact I\u0027d like to have down_read_no_lockdep() as well,\npercpu_down_read_recursive_readers() will need it.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Anton Arapov \u003canton@redhat.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Michal Marek \u003cmmarek@suse.cz\u003e\nCc: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nCc: \"Paul E.
