If lockd sends\na zero NSM state, but then a delayed SM_NOTIFY with a real NSM state\nnumber is received, there is no way for lockd or rpc.statd to\ndistinguish that stale SM_NOTIFY from an actual reboot. Thus lock\nrecovery could be performed after the rebooted host has already\nstarted reclaiming locks, and those locks will be lost.\n\nWe could change /etc/init.d/nfslock so it always modprobes lockd.ko\nbefore starting rpc.statd. However, if lockd.ko is ever unloaded\nand reloaded, we are back at square one, since the NSM state is not\npreserved across an unload/reload cycle. This may happen frequently\non clients that use automounter. A period of NFS inactivity causes\nlockd.ko to be unloaded, and the kernel loses its NSM state setting.\n\nInstead, let\u0027s use the fact that rpc.statd plants the local system\u0027s\nNSM state in every SM_MON (and SM_UNMON) reply. lockd performs a\nsynchronous SM_MON upcall to the local rpc.statd _before_ sending its\nfirst NLM request to a new remote. This would permit rpc.statd to\nprovide the current NSM state to lockd, even after lockd.ko had been\nunloaded and reloaded.\n\nNote that NLMPROC_LOCK arguments are constructed before the\nnsm_monitor() call, so we have to rearrange argument construction very\nslightly to make this all work out.\n\nAnd, the kernel appears to treat NSM state as a u32 (see struct\nnlm_args and nsm_res). Make nsm_local_state a u32 as well, to ensure\nwe don\u0027t get bogus comparison results.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "18fc31641925867c871bc75270ce642c039188d3", "tree": "2aad9b2c61fac3507526e41c719e1c989ad19a5e", "parents": [ "a21bdd9b960ccce421b63aa0e3efda4fcdc26f10" ], "author": { "name": "Chuck Lever", "email": "chuck.lever@oracle.com", "time": "Wed Jun 17 18:02:10 2009 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 17 18:02:10 2009 -0700" }, "message": "NFS: Fix false error return from nfs_callback_up() if ipv6.ko is not available\n\nClear \"ret\" if the error return from svc_create_xprt(AF_INET6) was\n-EAFNOSUPORT.

To address this, the following changes are made:\n\n* create generic functions which deal with manipulating the on-chip\n GPIO1/2 blocks. Such functions are universally useful.\n* Macros for GPIO2 shared interrupt management and block control.\n* support for both built-in CONFIG_GPIOLIB and fast, inlined GPIO macros.\n\n If CONFIG_GPIOLIB is not enabled, provide linux gpio framework\n compatibility by directly inlining the GPIO1/2 functions. GPIO access\n is limited to on-chip ones and they can be accessed as documented in\n the datasheets (GPIO0-31 and 200-215).\n\n If CONFIG_GPIOLIB is selected, two (2) gpio_chip-s, one for GPIO1 and\n one for GPIO2, are registered. GPIOs can still be accessed by using\n the numberspace established in the databooks.\n\n However this is not yet flexible enough for my uses: My Alchemy\n systems have a documented \"external\" gpio interface (fixed, different\n numberspace) and can support a variety of baseboards, some of which\n are equipped with I2C gpio expanders. I want to be able to provide\n the default 16 GPIOs of the CPU board numbered as 0..15 and also\n support gpio expanders, if present, starting as gpio16.\n\n To achieve this, a new Kconfig symbol for Alchemy is introduced,\n CONFIG_ALCHEMY_GPIO_INDIRECT, which boards can enable to signal\n that they don\u0027t want the Alchemy numberspace exposed to the outside\n world, but instead want to provide their own. Boards are now respon-\n sible for providing the linux gpio interface glue code (either in a\n custom gpio.h header (in board include directory) or with gpio_chips).\n\n To make the board-specific inlined gpio functions work, the MIPS\n Makefile must be changed so that the mach-au1x00/gpio.h header is\n included _after_ the board headers, by moving the inclusion of\n the mach-au1x00/ to the end of the header list.\n\n See arch/mips/include/asm/mach-au1x00/gpio.h for more info.\n\nSigned-off-by: Manuel Lauss \u003cmanuel.lauss@gmail.com\u003e\nAcked-by: Florian Fainelli \u003cflorian@openwrt.org\u003e\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "eeb09e6545bf68222798ccf3f355560a9e406435", "tree": "e265b5ab0d74c7aacb65da23cb07edc08cc6a6cb", "parents": [ "f203b7cacb96e4bb44b6995c03152cbedfb1857f" ], "author": { "name": "Manuel Lauss", "email": "manuel.lauss@googlemail.com", "time": "Sat Jun 06 14:09:54 2009 +0200" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Wed Jun 17 11:06:28 2009 +0100" }, "message": "MIPS: Alchemy: Remove unused au1000_gpio.h header\n\nSigned-off-by: Manuel Lauss \u003cmanuel.lauss@gmail.com\u003e\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "f203b7cacb96e4bb44b6995c03152cbedfb1857f", "tree": "d1ff4da5baa4828b2334fb2d671001b5f4a3d71d", "parents": [ "cc906f8e237770cf22d132dfa27ea586d67f7bf2" ], "author": { "name": "Matthieu Castet", "email": "castet.matthieu@free.fr", "time": "Sun May 24 19:48:51 2009 +0200" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Wed Jun 17 11:06:28 2009 +0100" }, "message": "MIPS: BCM47xx: Fix gpio_direction_output\n\ngpio_direction_output should also set an output value according to the API.\n\nSigned-off-by: Matthieu CASTET \u003ccastet.matthieu@free.fr\u003e \nAcked-by: Aurelien Jarno \u003caurelien@aurel32.net\u003e\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "cc906f8e237770cf22d132dfa27ea586d67f7bf2", "tree": "380eb1d90298b3de1b8494f94ccaacd06027ee3f", "parents": [ "923e3819005e60449ed6c9c8a86fd8e5cd9e6d77" ], "author": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Wed Jun 17 11:06:28 2009 +0100" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Wed Jun 17 11:06:28 2009 +0100" }, "message": "MIPS: ioctl.h: Cleanup.\n\n o Rewrite to use \u003casm-generic/ioctl.h\u003e.

From lmbench:\n\n\tProcessor, Processes - times in microseconds - smaller is better\n\t--------------------------------------------------------------------\n\tHost OS Mhz null null open slct fork exec sh\n\t call I/O stat clos TCP proc proc proc\n\t--------- ------------- ---- ---- ---- ---- ---- ---- ---- ---- ----\n - before:\n\tnehalem.l Linux 2.6.30- 3193 0.04 0.09 0.95 1.45 2.18 69.1 273. 1141\n\tnehalem.l Linux 2.6.30- 3193 0.04 0.09 0.95 1.48 2.28 69.9 253. 1140\n\tnehalem.l Linux 2.6.30- 3193 0.04 0.10 0.95 1.42 2.19 68.6 284. 1141\n - after:\n\tnehalem.l Linux 2.6.30- 3193 0.04 0.09 0.92 1.44 2.12 68.3 282. 1094\n\tnehalem.l Linux 2.6.30- 3193 0.04 0.09 0.92 1.39 2.20 67.0 308. 1123\n\tnehalem.l Linux 2.6.30- 3193 0.04 0.09 0.92 1.39 2.36 67.4 293. 1148\n\nwhere you can see what appears to be a roughly 3% improvement in stat\nand open/close latencies from just the removal of the locking overhead.\n\nOf course, this only matters for files you don\u0027t own (the owner never\nneeds to do the ACL checks), but that\u0027s the common case for libraries,\nheader files, and executables. As well as for the base components of any\nabsolute pathname, even if you are the owner of the final file.\n\n[ At some point we probably want to move this ACL caching logic entirely\n into the VFS layer (and only call down to the filesystem when\n uncached), but in the meantime this improves ext3 a bit.\n\n A similar fix to btrfs makes a much bigger difference (15x improvement\n in lmbench) due to broken caching. ]\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "65795efbd380a832ae508b04dba8f8e53f0b84d9", "tree": "a30261796868545d6b29ff062332433b460c3e2e", "parents": [ "8d15b0ec32f20a57881dc073b2e8d11dea0ccceb", "4eaad8ad296a78689f148c8dcd383fc4e51ee123" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 21:26:42 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 21:26:42 2009 -0700" }, "message": "Merge branch \u0027next-i2c\u0027 of git://aeryn.fluff.org.uk/bjdooks/linux\n\n* \u0027next-i2c\u0027 of git://aeryn.fluff.org.uk/bjdooks/linux:\n i2c-stu300: Make driver depend on MACH_U300\n i2c-s3c2410: use resource_size()\n i2c: Use resource_size macro\n i2c: ST DDC I2C U300 bus driver v3\n i2c-bfin-twi: pull in io.h for ioremap()\n" }, { "commit": "8d15b0ec32f20a57881dc073b2e8d11dea0ccceb", "tree": "8aa3d4dfd0660807c3ce2893b35292b3b0e3bf08", "parents": [ "005411c3e9147bc3b78215390e847d688dbbc163", "cc8da5263fa743c33d6503f85113bcb70048e633" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 21:20:39 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 21:20:39 2009 -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: switch to using late_initcall\n radeon legacy chips: tv dac bg/dac adj updates\n drm/radeon: introduce kernel modesetting for radeon hardware\n drm: Add the TTM GPU memory manager subsystem.\n drm: Memory fragmentation from lost alignment blocks\n drm/radeon: fix mobility flags on new PCI IDs.\n" }, { "commit": "005411c3e9147bc3b78215390e847d688dbbc163", "tree": "ed10cb7c73135fbdf7a39798bb0f294e80f987a4", "parents": [ "519d25679e8ae7433c758b9e74b19144f61b90f8" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Jun 16 21:36:49 2009 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 21:20:14 2009 -0700" }, "message": "AFS: Correctly translate auth error aborts and don\u0027t failover in such cases\n\nAuthentication error abort codes should be translated to appropriate\nLinux error codes, rather than all being translated to EREMOTEIO - which\nindicates that the server had internal problems.\n\nAdditionally, a server shouldn\u0027t be marked unavailable and the next\nserver tried if an authentication error occurs.
