This means that\nif sys_restart_syscall() actually happens and it is interrupted as well, we\ndon\u0027t update the user-space variable, but write into the already dead stack\nframe.\n\nIntroduced by commit 04c227140fed77587432667a574b14736a06dd7f\nhrtimer: Rework hrtimer_nanosleep to make sys_compat_nanosleep easier\n\nChange the callers to pass \"__user *rmtp\" to hrtimer_nanosleep(), and change\nhrtimer_nanosleep() to use copy_to_user() to actually update *rmtp.\n\nSmall problem remains. man 2 nanosleep states that *rtmp should be written if\nnanosleep() was interrupted (it says nothing whether it is OK to update *rmtp\nif nanosleep returns 0), but (with or without this patch) we can dirty *rem\neven if nanosleep() returns 0.\n\nNOTE: this patch doesn\u0027t change compat_sys_nanosleep(), because it has other\nbugs. Fixed by the next patch.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Alexey Dobriyan \u003cadobriyan@sw.ru\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nCc: Pavel Emelyanov \u003cxemul@sw.ru\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Toyo Abe \u003ctoyoa@mvista.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n\n include/linux/hrtimer.h | 2 -\n kernel/hrtimer.c | 51 +++++++++++++++++++++++++-----------------------\n kernel/posix-timers.c | 14 +------------\n 3 files changed, 30 insertions(+), 37 deletions(-)\n\n" }, { "commit": "e13a2e61dd5152f5499d2003470acf9c838eab84", "tree": "4846b2ea392773f7a92d31334295d7aadbafd83e", "parents": [ "25f666300625d894ebe04bac2b4b3aadb907c861" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Sun Feb 10 10:48:03 2008 +0100" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sun Feb 10 10:48:03 2008 +0100" }, "message": "ntp: correct inconsistent interval/tick_length usage\n\nclocksource initialization and error accumulation.

The intervening result, however, is\nsubject to overflows, especially since the fraction is not simplified (for\nHZ \u003d\u003d 300, we multiply by 300 and divide by 1000).\n\nThis is exposed to the user when passing a large timeout to poll(), for\nexample.\n\nThis patch replaces the multiply-divide with a reciprocal multiplication on\n32-bit platforms. When the input is an unsigned long, there is no portable\nway to do this on 64-bit platforms there is no portable way to do this\nsince it requires a 128-bit intermediate result (which gcc does support on\n64-bit platforms but may generate libgcc calls, e.g. on 64-bit s390), but\nsince the output is a 32-bit integer in the cases affected, just simplify\nthe multiply-divide (*3/10 instead of *300/1000).\n\nThe reciprocal multiply used can have off-by-one errors in the upper half\nof the valid output range. This could be avoided at the expense of having\nto deal with a potential 65-bit intermediate result. Since the intent is\nto avoid overflow problems and most of the other time conversions are only\nsemiexact, the off-by-one errors were considered an acceptable tradeoff.\n\nAt Ralf Baechle\u0027s suggestion, this version uses a Perl script to compute\nthe necessary constants. We already have dependencies on Perl for kernel\ncompiles. This does, however, require the Perl module Math::BigInt, which\nis included in the standard Perl distribution starting with version 5.8.0.\nIn order to support older versions of Perl, include a table of canned\nconstants in the script itself, and structure the script so that\nMath::BigInt isn\u0027t required if pulling values from said table.\n\nRunning the script requires that the HZ value is available from the\nMakefile. Thus, this patch also adds the Kconfig variable CONFIG_HZ to the\narchitectures which didn\u0027t already have it (alpha, cris, frv, h8300, m32r,\nm68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or\nsh64 architectures, since Paul Mundt has dealt with those separately in the\nsh tree.\n\nSigned-off-by: H.

However,\nit was the \"only if\" half of the conjunction that was most interesting.\nReword to emphasis the \"only if\" aspect.\n\nThe locking comment for remove_tasks_in_empty_cpuset() was wrong; it said\ncallback_mutex had to be held on entry. The opposite is true.\n\nSeveral mentions of attach_task() in comments needed to be\nchanged to cgroup_attach_task().\n\nA comment about notify_on_release was no longer relevant,\nas the line of code it had commented, namely:\n\tset_bit(CS_RELEASED_RESOURCE, \u0026parent-\u003eflags);\nis no longer present in that place in the cpuset.c code.\n\nSimilarly a comment about notify_on_release before the\nscan_for_empty_cpusets() routine was no longer relevant.\n\nRemoved extra parentheses and unnecessary return statement.\n\nRenamed attach_task() to cpuset_attach() in various comments.\n\nRemoved comment about not needing memory migration, as it seems the migration\nis done anyway, via the cpuset_attach() callback from cgroup_attach_task().\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nAcked-by: Cliff Wickman \u003ccpw@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2df167a300d7b3ab9949bbb02a8f604afd809b92", "tree": "786c9f13787b828dcaef38e5f73cb946c5301946", "parents": [ "58f4790b73639d1fa808439fac7f761a4c46e11f" ], "author": { "name": "Paul Menage", "email": "menage@google.com", "time": "Thu Feb 07 00:14:45 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Feb 07 08:42:22 2008 -0800" }, "message": "cgroups: update comments in cpuset.c\n\nSome of the comments in kernel/cpuset.c were stale following the\ntransition to control groups; this patch updates them to more closely\nmatch reality.\n\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nAcked-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "58f4790b73639d1fa808439fac7f761a4c46e11f", "tree": "2c7a9cbee80de78beed07b0915df649d8e843365", "parents": [ "956db3ca0606e78456786ef19fd4dc7a5151a6e1" ], "author": { "name": "Cliff Wickman", "email": "cpw@sgi.com", "time": "Thu Feb 07 00:14:44 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Feb 07 08:42:22 2008 -0800" }, "message": "cpusets: update_cpumask revision\n\nUse the new function cgroup_scan_tasks() to step through all tasks in a\ncpuset.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Cliff Wickman \u003ccpw@sgi.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Paul Jackson \u003cpj@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "956db3ca0606e78456786ef19fd4dc7a5151a6e1", "tree": "0bef3d107df1115ecf76e342f30ecee67a7f3705", "parents": [ "31a7df01fd0cd786f60873a921aecafac148c290" ], "author": { "name": "Cliff Wickman", "email": "cpw@sgi.com", "time": "Thu Feb 07 00:14:43 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Feb 07 08:42:22 2008 -0800" }, "message": "hotplug cpu: move tasks in empty cpusets to parent\n\nThis patch corrects a situation that occurs when one disables all the cpus in\na cpuset.\n\nCurrently, the disabled (cpu-less) cpuset inherits the cpus of its parent,\nwhich is incorrect because it may then overlap its cpu-exclusive sibling.\n\nTasks of an empty cpuset should be moved to the cpuset which is the parent of\ntheir current cpuset.
