      "message": "taskstats: pad taskstats netlink response for aligment issues on ia64\n\nThe taskstats structure is internally aligned on 8 byte boundaries but the\nlayout of the aggregrate reply, with two NLA headers and the pid (each 4\nbytes), actually force the entire structure to be unaligned.  This causes\nthe kernel to issue unaligned access warnings on some architectures like\nia64.  Unfortunately, some software out there doesn\u0027t properly unroll the\nNLA packet and assumes that the start of the taskstats structure will\nalways be 20 bytes from the start of the netlink payload.  Aligning the\nstart of the taskstats structure breaks this software, which we don\u0027t\nwant.  So, for now the alignment only happens on architectures that\nrequire it and those users will have to update to fixed versions of those\npackages.  Space is reserved in the packet only when needed.  This ifdef\nshould be removed in several years e.g.  2012 once we can be confident\nthat fixed versions are installed on most systems.  We add the padding\nbefore the aggregate since the aggregate is already a defined type.\n\nCommit 85893120 (\"delayacct: align to 8 byte boundary on 64-bit systems\")\npreviously addressed the alignment issues by padding out the pid field.\nThis was supposed to be a compatible change but the circumstances\ndescribed above mean that it wasn\u0027t.  This patch backs out that change,\nsince it was a hack, and introduces a new NULL attribute type to provide\nthe padding.  Padding the response with 4 bytes avoids allocating an\naligned taskstats structure and copying it back.  Since the structure\nweighs in at 328 bytes, it\u0027s too big to do it on the stack.\n\nSigned-off-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\nReported-by: Brian Rogers \u003cbrian@xyzw.org\u003e\nCc: Jeff Mahoney \u003cjeffm@suse.com\u003e\nCc: Guillaume Chazarain \u003cguichaz@gmail.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "delay-accounting: reimplement -c for getdelays.c to report information on a target command\n\nTask delay-accounting was identified as one means of determining how long\na process spends in congestion_wait() without adding new statistics.  For\nexample, if the workload should not be doing IO, delay-accounting could\nreveal how long it was spending in unexpected IO or delays.\nUnfortunately, on closer examination it was clear that getdelays does not\nact as documented.\n\nCommit a3baf649 (\"per-task-delay-accounting: documentation\") added\nDocumentation/accounting/getdelays.c with a -c switch that was documented\nto fork/exec a child and report statistics on it but for reasons that are\nunclear to me, commit 9e06d3f9 deleted support for this switch but did not\nupdate the documentation.  It might be an oversight or it might be because\nthe control flow of the program meant that accounting information would be\nprinted once early in the lifetime of the program making it of limited\nuse.\n\nThis patch reimplements -c for getdelays.c to act as documented.  Unlike\nthe original version, it waits until the command completes before printing\nany information on it.  An example of it being used looks like\n\n$ ./getdelays -d -c find /home/mel -name mel\nprint delayacct stats ON\n/home/mel\n/home/mel/.notes-wine/drive_c/windows/profiles/mel\n/home/mel/.wine/drive_c/windows/profiles/mel\n/home/mel/git-configs/dot.kde/share/apps/konqueror/home/mel\nPID\t5923\n\nCPU             count     real total  virtual total    delay total\n                42779     5051232096     5164722692      564207988\nIO              count    delay total\n                41727    97804147758\nSWAP            count    delay total\n                    0              0\nRECLAIM         count    delay total\n                    0              0\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The\npatch is on top of 2.6.21-mm1 with Paul\u0027s cgroups v9 patches (forward\nported)\n\nThis patch implements per cgroup statistics infrastructure and re-uses\ncode from the taskstats interface.  A new set of cgroup operations are\nregistered with commands and attributes.  It should be very easy to\n*extend* per cgroup statistics, by adding members to the cgroupstats\nstructure.\n\nThe current model for cgroupstats is a pull, a push model (to post\nstatistics on interesting events), should be very easy to add.  Currently\nuser space requests for statistics by passing the cgroup file\ndescriptor.  Statistics about the state of all the tasks in the cgroup\nis returned to user space.\n\nTODO\u0027s/NOTE:\n\nThis patch provides an infrastructure for implementing cgroup statistics.\nBased on the needs of each controller, we can incrementally add more statistics,\nevent based support for notification of statistics, accumulation of taskstats\ninto cgroup statistics in the future.\n\nSample output\n\n# ./cgroupstats -C /cgroup/a\nsleeping 2, blocked 0, running 1, stopped 0, uninterruptible 0\n\n# ./cgroupstats -C /cgroup/\nsleeping 154, blocked 0, running 0, stopped 0, uninterruptible 0\n\nIf the approach looks good, I\u0027ll enhance and post the user space utility for\nthe same\n\nFeedback, comments, test results are always welcome!\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Jay Lan \u003cjlan@engr.sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "[PATCH] delay accounting taskstats interface send tgid once\n\nSend per-tgid data only once during exit of a thread group instead of once\nwith each member thread exit.\n\nCurrently, when a thread exits, besides its per-tid data, the per-tgid data\nof its thread group is also sent out, if its thread group is non-empty.\nThe per-tgid data sent consists of the sum of per-tid stats for all\n*remaining* threads of the thread group.\n\nThis patch modifies this sending in two ways:\n\n- the per-tgid data is sent only when the last thread of a thread group\n  exits.  This cuts down heavily on the overhead of sending/receiving\n  per-tgid data, especially when other exploiters of the taskstats\n  interface aren\u0027t interested in per-tgid stats\n\n- the semantics of the per-tgid data sent are changed.  Instead of being\n  the sum of per-tid data for remaining threads, the value now sent is the\n  true total accumalated statistics for all threads that are/were part of\n  the thread group.\n\nThe patch also addresses a minor issue where failure of one accounting\nsubsystem to fill in the taskstats structure was causing the send of\ntaskstats to not be sent at all.\n\nThe patch has been tested for stability and run cerberus for over 4 hours\non an SMP.\n\n[akpm@osdl.org: bugfixes]\nSigned-off-by: Shailabh Nagar \u003cnagar@watson.ibm.com\u003e\nSigned-off-by: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Jay Lan \u003cjlan@engr.sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
