They are required\nbecause some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS\nfor example. The 64-bit inode numbers are then propagated to userspace\nautomatically where the arch supports it.\n\nProblems have been seen with userspace (eg: ld.so) using the 64-bit inode\nnumber returned by stat64() or getdents64() to differentiate files, and\nfailing because the 64-bit inode number space was compressed to 32-bits, and\nso overlaps occur.\n\nThis patch:\n\nMake filldir_t take a 64-bit inode number and struct kstat carry a 64-bit\ninode number so that 64-bit inode numbers can be passed back to userspace.\n\nThe stat functions then returns the full 64-bit inode number where\navailable and where possible. If it is not possible to represent the inode\nnumber supplied by the filesystem in the field provided by userspace, then\nerror EOVERFLOW will be issued.\n\nSimilarly, the getdents/readdir functions now pass the full 64-bit inode\nnumber to userspace where possible, returning EOVERFLOW instead when a\ndirectory entry is encountered that can\u0027t be properly represented.\n\nNote that this means that some inodes will not be stat\u0027able on a 32-bit\nsystem with old libraries where they were before - but it does mean that\nthere will be no ambiguity over what a 32-bit inode number refers to.\n\nNote similarly that directory scans may be cut short with an error on a\n32-bit system with old libraries where the scan would work before for the\nsame reasons.\n\nIt is judged unlikely that this situation will occur because modern glibc\nuses 64-bit capable versions of stat and getdents class functions\nexclusively, and that older systems are unlikely to encounter\nunrepresentable inode numbers anyway.\n\n[akpm: alpha build fix]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1d32849b14bc8792e6f35ab27dd990d74b16126c", "tree": "caba51ce9df60e42412119063e582023a534507e", "parents": [ "ad7a3bf30c27d902042bc85c3e54eb2082d633bd" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Tue Oct 03 01:13:45 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Oct 03 08:03:40 2006 -0700" }, "message": "[PATCH] pid.h cleanup\n\nMake the pid.h macros look less revolting in an 80-col window.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0235497f7a961db57ef975eb889503809ce82fe5", "tree": "db9f912d23d574bfa97c0ce4def19188e1f9b155", "parents": [ "95f3eff6997ae4a6754c1d874ec0a414d97c44d1" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Oct 02 14:05:20 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Oct 02 14:05:20 2006 -0700" }, "message": "Add prototype for sigset_from_compat()\n\nDuh.

For this race to trigger the process that proc_pid_readdir stops at\nmust exit before readdir is called again.\n\nThis can cause ps to fail to report processes, and it is in violation of\nposix guarantees and normal application expectations with respect to\nreaddir.\n\nCurrently there is no way to work around this problem in user space short\nof providing a gargantuan buffer to user space so the directory read all\nhappens in on system call.\n\nThis patch implements the normal directory semantics for proc, that\nguarantee that a directory entry that is neither created nor destroyed\nwhile reading the directory entry will be returned. For directory that are\neither created or destroyed during the readdir you may or may not see them.\n Furthermore you may seek to a directory offset you have previously seen.\n\nThese are the guarantee that ext[23] provides and that posix requires, and\nmore importantly that user space expects. Plus it is a simple semantic to\nimplement reliable service. It is just a matter of calling readdir a\nsecond time if you are wondering if something new has show up.\n\nThese better semantics are implemented by scanning through the pids in\nnumerical order and by making the file offset a pid plus a fixed offset.\n\nThe pid scan happens on the pid bitmap, which when you look at it is\nremarkably efficient for a brute force algorithm. Given that a typical\ncache line is 64 bytes and thus covers space for 64*8 \u003d\u003d 200 pids. There\nare only 40 cache lines for the entire 32K pid space. A typical system\nwill have 100 pids or more so this is actually fewer cache lines we have to\nlook at to scan a linked list, and the worst case of having to scan the\nentire pid bitmap is pretty reasonable.\n\nIf we need something more efficient we can go to a more efficient data\nstructure for indexing the pids, but for now what we have should be\nsufficient.\n\nIn addition this takes no additional locks and is actually less code than\nwhat we are doing now.\n\nAlso another very subtle bug in this area has been fixed. It is possible\nto catch a task in the middle of de_thread where a thread is assuming the\nthread of it\u0027s thread group leader.

The previous patches already increased the\nresolution and precision of the computations, so that this conversion becomes\nquite simple.\n\n\u003clinux@horizon.com\u003e explains:\n\nThe original NTP kernel interface was defined in units of microseconds.\nThat\u0027s what Linux implements. As computers have gotten faster and can now\nsplit microseconds easily, a new kernel interface using nanosecond units was\ndefined (\"the nanokernel\", confusing as that name is to OS hackers), and\nthere\u0027s an STA_NANO bit in the adjtimex() status field to tell the application\nwhich units it\u0027s using.\n\nThe current ntpd supports both, but Linux loses some possible timing\nresolution because of quantization effects, and the ntpd hackers would really\nlike to be able to drop the backwards compatibility code.\n\nUlrich Windl has been maintaining a patch set to do the conversion for years,\nbut it\u0027s hard to keep in sync.\n\nSigned-off-by: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "04b617e71e363e640e88be1e43f53fa6a3afef9f", "tree": "b59e8e75e4671bc5e10f4fcaace85d4658d4d0f0", "parents": [ "97eebe138caaf78354b1fad233e63bafdcc4fd54" ], "author": { "name": "Roman Zippel", "email": "zippel@linux-m68k.org", "time": "Sat Sep 30 23:28:27 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:27 2006 -0700" }, "message": "[PATCH] ntp: convert time_freq to nsec value\n\nThis converts time_freq to a scaled nsec value and adds around 6bit of extra\nresolution.

The\ncode that today makes this tradeoff just does a rather simple algorithm;\nhowever this is not good enough: There are devices and use cases where a\nlower latency is required than that the higher power saving states provide.\n An example would be audio playback, but another example is the ipw2100\nwireless driver that right now has a very direct and ugly acpi hook to\ndisable some higher power states randomly when it gets certain types of\nerror.\n\nThe proposed solution is to have an interface where drivers can\n\n* announce the maximum latency (in microseconds) that they can deal with\n* modify this latency\n* give up their constraint\n\nand a function where the code that decides on power saving strategy can\nquery the current global desired maximum.\n\nThis patch has a user of each side: on the consumer side, ACPI is patched\nto use this, on the producer side the ipw2100 driver is patched.\n\nA generic maximum latency is also registered of 2 timer ticks (more and you\nlose accurate time tracking after all).\n\nWhile the existing users of the patch are x86 specific, the infrastructure\nis not.
