This patch reduces the rate by a factor of about 70.\nLow enough that we didn\u0027t care to further investigate the issue.\n\nPerformance impact with any sort of \"normal\" use was ~2%+ CPU and less\nthan 1% throughput degradation. Worst case impact (cached read) was\n6% IOPS reduction. This is with NCQ off (q\u003d1) but I believe FIS based\nswitching enabled in the SATA driver.\n\nThe patch disables \"Early ACK\" in the 3726 port multiplier.\n\"Early ACK\" is issued when device sends a FIS to the host (via PMP)\nand the PMP sends an ACK immediately back to the device - well before\nthe host gets the response. Under worst case IOPs load (cached read\ntest) and more than 2 PMPs connected to a 4-port SATA controller,\nI suspect the time to service all of the PMPs is exceeding the PMPs\nability to keep track of outstanding FIS it owes the Host. Reducing\nthe number of PMPs to 2 (or 1) reduces the frequency by several orders\nof magnitude. Kudos to Gwendal for initial debugging of this issue.\n[Any errors in the description are mine, not his.]\n\nPatch is currently in production on Google servers.\n\nSigned-off-by: Grant Grundler \u003cgrundler@google.com\u003e\nSigned-off-by: Gwendal Grignou \u003cgwendal@google.com\u003e\nAcked-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "fbaf666b854c04b2d8ebca17114ee409ddea08b5", "tree": "8e4db33f928eb3554b1539d9745fedb01391df6a", "parents": [ "83f2b9630c5875ee872c11d98a0e26888514c1b3" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Tue Mar 30 02:52:43 2010 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Fri May 14 17:08:02 2010 -0400" }, "message": "libata: update gfp/slab.h includes\n\nImplicit slab.h inclusion via percpu.h is about to go away.

Interrupts\nshould be hard-disabled at this point but they were enabled. Because\nthe interrupt was not recoverable the system panicked.\n\nThe reason is that the exception exit path was calling\nperf_event_do_pending after hard-disabling interrupts, and\nperf_event_do_pending will re-enable interrupts.\n\nThe simplest and cleanest fix for this is to use the same mechanism\nthat 32-bit powerpc does, namely to cause a self-IPI by setting the\ndecrementer to 1. This means we can remove the tests in the exception\nexit path and raw_local_irq_restore.\n\nThis also makes sure that the call to perf_event_do_pending from\ntimer_interrupt() happens within irq_enter/irq_exit. (Note that\ncalling perf_event_do_pending from timer_interrupt does not mean that\nthere is a possible 1/HZ latency; setting the decrementer to 1 ensures\nthat the timer interrupt will happen immediately, i.e. within one\ntimebase tick, which is a few nanoseconds or 10s of nanoseconds.)\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: stable@kernel.org\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "e84346b726ea90a8ed470bc81c4136a7b8710ea5", "tree": "99a90ef86d38a51e39ed69af318e6cfe32023879", "parents": [ "f818a73674c5d197f66b636a46d7d578d7258129" ], "author": { "name": "Sage Weil", "email": "sage@newdream.net", "time": "Tue May 11 21:20:38 2010 -0700" }, "committer": { "name": "Sage Weil", "email": "sage@newdream.net", "time": "Tue May 11 21:20:38 2010 -0700" }, "message": "ceph: preserve seq # on requeued messages after transient transport errors\n\nIf the tcp connection drops and we reconnect to reestablish a stateful\nsession (with the mds), we need to resend previously sent (and possibly\nreceived) messages with the _same_ seq # so that they can be dropped on\nthe other end if needed.

When a share spans multiple filesystems, it\u0027s\nquite possible that there will be collisions. This is a server bug, but\nwhen the inodes in question are a directory (as is often the case) and\nthere is a collision with the root inode of the mount, the result is a\nkernel panic on umount.\n\nFix this by checking explicitly for directory inodes with the same\nuniqueid. If that is the case, then we can assume that using server inode\nnumbers will be a problem and that they should be disabled.\n\nFixes Samba bugzilla 7407\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nCC: Stable \u003cstable@kernel.org\u003e\nReviewed-and-Tested-by: Suresh Jayaraman \u003csjayaraman@suse.de\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "fc2a093e7ad23e935aa29e349bc27173c92f1a95", "tree": "3890ad9a113ab199c3b50170d7590c796268f0be", "parents": [ "9fc282baa8f743a7049e301d13cf9968ee95a91c", "c9ff04c941d2cd87d27496d7fee8923238bb2ebb" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 11 10:12:18 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 11 10:12:18 2010 -0700" }, "message": "Merge branch \u0027drm-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6\n\n* \u0027drm-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:\n drm/radeon: Fix 3 regressions - since buffer rework\n" }, { "commit": "9fc282baa8f743a7049e301d13cf9968ee95a91c", "tree": "d34e827ed35c21b98eb4e3d4c3731d1da54fa03a", "parents": [ "c61ea31dac0319ec64b33725917bda81fc293a25", "de02d72bb3cc5b3d4c873db4ca8291723dd48479" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 11 10:11:40 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 11 10:11:40 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:\n net: Fix FDDI and TR config checks in ipv4 arp and LLC.\n IPv4: unresolved multicast route cleanup\n mac80211: remove association work when processing deauth request\n ar9170: wait for asynchronous firmware loading\n ipv4: udp: fix short packet and bad checksum logging\n phy: Fix initialization in micrel driver.\n sctp: Fix a race between ICMP protocol unreachable and connect()\n veth: Dont kfree_skb() after dev_forward_skb()\n IPv6: fix IPV6_RECVERR handling of locally-generated errors\n net/gianfar: drop recycled skbs on MTU change\n iwlwifi: work around passive scan issue\n" }, { "commit": "c61ea31dac0319ec64b33725917bda81fc293a25", "tree": "05a4f3011ea8b334795aae606d89bcf27e3e26c5", "parents": [ "7d6fb7bd1919517937ec390f6ca2d7bcf4f89fb6" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue May 11 16:51:39 2010 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 11 10:07:53 2010 -0700" }, "message": "CacheFiles: Fix occasional EIO on call to vfs_unlink()\n\nFix an occasional EIO returned by a call to vfs_unlink():\n\n\t[ 4868.465413] CacheFiles: I/O Error: Unlink failed\n\t[ 4868.465444] FS-Cache: Cache cachefiles stopped due to I/O error\n\t[ 4947.320011] CacheFiles: File cache on md3 unregistering\n\t[ 4947.320041] FS-Cache: Withdrawing cache \"mycache\"\n\t[ 5127.348683] FS-Cache: Cache \"mycache\" added (type cachefiles)\n\t[ 5127.348716] CacheFiles: File cache on md3 registered\n\t[ 7076.871081] CacheFiles: I/O Error: Unlink failed\n\t[ 7076.871130] FS-Cache: Cache cachefiles stopped due to I/O error\n\t[ 7116.780891] CacheFiles: File cache on md3 unregistering\n\t[ 7116.780937] FS-Cache: Withdrawing cache \"mycache\"\n\t[ 7296.813394] FS-Cache: Cache \"mycache\" added (type cachefiles)\n\t[ 7296.813432] CacheFiles: File cache on md3 registered\n\nWhat happens is this:\n\n (1) A cached NFS file is seen to have become out of date, so NFS retires the\n object and immediately acquires a new object with the same key.\n\n (2) Retirement of the old object is done asynchronously - so the lookup/create\n to generate the new object may be done first.\n\n This can be a problem as the old object and the new object must exist at\n the same point in the backing filesystem (i.e. they must have the same\n pathname).\n\n (3) The lookup for the new object sees that a backing file already exists,\n checks to see whether it is valid and sees that it isn\u0027t.
