So introduce\n-\u003eupdate_time, where we will deal with i_version an a/m/c time updates and\nindicate which changes need to be made. The normal version just does what it\nhas always done, updates the time and marks the inode dirty, and then\nfilesystems can choose to do something different.\n\nI\u0027ve gone through all of the users of file_update_time and made them check for\nerrors with the exception of the fault code since it\u0027s complicated and I wasn\u0027t\nquite sure what to do there, also Jan is going to be pushing the file time\nupdates into page_mkwrite for those who have it so that should satisfy btrfs and\nmake it not a big deal to check the file_update_time() return code in the\ngeneric fault path.

By\nincreasing the default maximums and not realising they were tied to any\nattempt to create a message queue without an attribute struct, I had\ninadvertently made it such that all message queue creation attempts\nwithout an attribute struct were failing because the new default\nmaximums would create a queue that exceeded the default rlimit for\nmessage queue bytes.\n\nAs a result, the system wide defaults were brought back down to their\nprevious levels, and the system wide ceilings on the maximums were\nraised to meet the customer\u0027s needs. However, the fact that the no\nattribute struct behavior of mq_open() could be broken by changing the\nsystem wide maximums for message queues was seen as fundamentally broken\nitself. So we hardwired the no attribute case back like it used to be.\nBut, then we realized that on the very off chance that some piece of\nsoftware in the wild depended on that behavior, we could work around\nthat issue by adding two new knobs to /proc that allowed setting the\ndefaults for message queues created without an attr struct separately\nfrom the system wide maximums.\n\nWhat is not an option IMO is to leave the current behavior in place. No\npiece of software should ever rely on setting the system wide maximums\nin order to get a desired message queue. Such a reliance would be so\nfundamentally multitasking OS unfriendly as to not really be tolerable.\nFortunately, we don\u0027t know of any software in the wild that uses this\nexcept for a regression test program that caught the issue in the first\nplace. If there is though, we have made accommodations with the two new\n/proc knobs (and that\u0027s all the accommodations such fundamentally broken\nsoftware can be allowed)..\n\nThis patch:\n\nThe various defines for minimums and maximums of the sysctl controllable\nmqueue values are scattered amongst different files and named\ninconsistently.

This\nkernel thread wakes up every 5 seconds (by default) and calls\n\u0027-\u003ewrite_super()\u0027 for all mounted file-systems.

The PPF uses the phys capabilities when it computes things\n like ICM size.\n\n The dev_caps structure will then contain the paravirtualized values, making\n bookkeeping much easier in SRIOV mode. We add a structure rather than a\n single parameter because there will be other fields in the phys_caps.\n\n The first field we add to the mlx4_phys_caps structure is num_phys_eqs.\n\n2. In INIT_HCA, when running in SRIOV mode, the \"log_num_eqs\" parameter\n passed to the FW is the number of EQs per VF/PF; each function (PF or VF)\n has this number of EQs available.\n\n However, the total number of EQs which must be allowed for in the ICM is\n (1 \u003c\u003c log_num_eqs) * (#VFs + #PFs). Rather than compute this quantity,\n we allocate ICM space for 1024 EQs (which is the device maximum\n number of EQs, and which is the value we place in the mlx4_phys_caps structure).\n\n For INIT_HCA, however, we use the per-function number of EQs as described\n above.\n\nSigned-off-by: Marcel Apfelbaum \u003cmarcela@dev.mellanox.co.il\u003e\nSigned-off-by: Jack Morgenstein \u003cjackm@dev.mellanox.co.il\u003e\nReviewed-by: Or Gerlitz \u003cogerlitz@mellanox.com\u003e\nSigned-off-by: David S.

On this set, it changes the Kernel EDAC API in order\n to properly represent the Intel i3/i5/i7, Xeon 3xxx/5xxx/7xxx, and\n Intel E5-xxxx memory controllers.\n\n The EDAC core used to assume that:\n\n - the DRAM chip select pin is directly accessed by the memory\n controller\n\n - when multiple channels are used, they\u0027re all filled with the\n same type of memory.\n\n None of the above premises is true on Intel memory controllers since\n 2002, when RAMBUS and FB-DIMMs were introduced, and Advanced Memory\n Buffer or by some similar technologies hides the direct access to the\n DRAM pins.\n\n So, the existing drivers for those chipsets had to lie to the EDAC\n core, in general telling that just one channel is filled. That\n produces some hard to understand error messages like:\n\n EDAC MC0: CE row 3, channel 0, label \"DIMM1\": 1 Unknown error(s): memory read error on FATAL area : cpu\u003d0 Err\u003d0008:00c2 (ch\u003d2), addr \u003d 0xad1f73480 \u003d\u003e socket\u003d0, Channel\u003d0(mask\u003d2), rank\u003d1\n\n The location information there (row3 channel 0) is completely bogus:\n it has no physical meaning, and are just some random values that the\n driver uses to talk with the EDAC core. The error actually happened\n at CPU socket 0, channel 0, slot 1, but this is not reported anywhere,\n as the EDAC core doesn\u0027t know anything about the memory layout. So,\n only advanced users that know how the EDAC driver works and that tests\n their systems to see how DIMMs are mapped can actually benefit for\n such error logs.\n\n This patch series fixes the error report logic, in order to allow the\n EDAC to expose the memory architecture used by them to the EDAC core.\n So, as the EDAC core now understands how the memory is organized, it\n can provide an useful report:\n\n EDAC MC0: CE memory read error on DIMM1 (channel:0 slot:1 page:0x364b1b offset:0x600 grain:32 syndrome:0x0 - count:1 area:DRAM err_code:0001:0090 socket:0 channel_mask:1 rank:4)\n\n The location of the DIMM where the error happened is reported by \"MC0\"\n (cpu socket #0), at \"channel:0 slot:1\" location, and matches the\n physical location of the DIMM.\n\n There are two remaining issues not covered by this patch series:\n\n - The EDAC sysfs API will still report bogus values. So,\n userspace tools like edac-utils will still use the bogus data;\n\n - Add a new tracepoint-based way to get the binary information\n about the errors.\n\n Those are on a second series of patches (also at -next), but will\n probably miss the train for 3.5, due to the slow review process.\"\n\nFix up trivial conflict (due to spelling correction of removed code) in\ndrivers/edac/edac_device.c\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac: (42 commits)\n i7core: fix ranks information at the per-channel struct\n i5000: Fix the fatal error handling\n i5100_edac: Fix a warning when compiled with 32 bits\n i82975x_edac: Test nr_pages earlier to save a few CPU cycles\n e752x_edac: provide more info about how DIMMS/ranks are mapped\n i5000_edac: Fix the logic that retrieves memory information\n i5400_edac: improve debug messages to better represent the filled memory\n edac: Cleanup the logs for i7core and sb edac drivers\n edac: Initialize the dimm label with the known information\n edac: Remove the legacy EDAC ABI\n x38_edac: convert driver to use the new edac ABI\n tile_edac: convert driver to use the new edac ABI\n sb_edac: convert driver to use the new edac ABI\n r82600_edac: convert driver to use the new edac ABI\n ppc4xx_edac: convert driver to use the new edac ABI\n pasemi_edac: convert driver to use the new edac ABI\n mv64x60_edac: convert driver to use the new edac ABI\n mpc85xx_edac: convert driver to use the new edac ABI\n i82975x_edac: convert driver to use the new edac ABI\n i82875p_edac: convert driver to use the new edac ABI\n ...\n" }, { "commit": "7e5b2db77b05746613516599c916a8cc2e321077", "tree": "c3ec333ff7b77bcc8e456a3a3d19bf20f5c651b8", "parents": [ "227d1e4319ffd8729781941d92f4ae4d85beecd9", "c819baf31f5f91fbb06b2c93de2d5b8c8d096f3f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 29 18:27:19 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 29 18:27:19 2012 -0700" }, "message": "Merge branch \u0027upstream\u0027 of git://git.linux-mips.org/pub/scm/ralf/upstream-linus\n\nPull MIPS updates from Ralf Baechle:\n \"The whole series has been sitting in -next for quite a while with no\n complaints.
