With\nthis new patch, fixing this bug was as simple as adding the\nEXT4_FREE_BLOCKS_FORGET flags to the call to ext4_free_blocks().\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: \"Aneesh Kumar K.V\" \u003caneesh.kumar@linux.vnet.ibm.com\u003e\n" }, { "commit": "beac2da7565e42be59963824899825d0cc624295", "tree": "22b38198349bd000cd146243271f604708fbc3fb", "parents": [ "cf40db137cc2b2a1b3f6850247ac2b181d9d3847" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Nov 23 07:25:08 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Nov 23 07:25:08 2009 -0500" }, "message": "ext4: add tracepoint for ext4_forget()\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "67178767b936fb47a3a5e88097cff41ccbda7acb", "tree": "f55675817e8d934bd2a627a729a010a58bbba464", "parents": [ "db48cccc7c709ccfa7cb4ac702bc27c216bffee7" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Fri Nov 13 10:06:34 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Nov 13 10:48:27 2009 +0100" }, "message": "tracing: Rename \u0027lockdep\u0027 event subsystem into \u0027lock\u0027\n\nLockdep events subsystem gathers various locking related events\nsuch as a request, release, contention or acquisition of a lock.\n\nThe name of this event subsystem is a bit of a misnomer since\nthese events are not quite related to lockdep but more generally\nto locking, ie: these events are not reporting lock dependencies\nor possible deadlock scenario but pure locking events.\n\nHence this rename.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nAcked-by: Hitoshi Mitake \u003cmitake@dcl.info.waseda.ac.jp\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nLKML-Reference: \u003c1258103194-843-1-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "9de09ace8d518141a4375e1d216ab64db4377799", "tree": "da8e7a77f4ea91eb3bb73fc6da72ecf8c99e1c16", "parents": [ "1beee96bae0daf7f491356777c3080cc436950f5", "6d3f1e12f46a2f9a1bb7e7aa433df8dd31ce5647" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Oct 29 09:02:15 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Oct 29 09:02:20 2009 +0100" }, "message": "Merge branch \u0027tracing/urgent\u0027 into tracing/core\n\nMerge reason: Pick up fixes and move base from -rc1 to -rc5.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "434a83c3fbb951908a3a52040f7f0e0b8ba00dd0", "tree": "2b0d75112d6f132e749024c2a61a806426a2ac06", "parents": [ "a66abe7fbf7805a1a02f241bd5283265ff6706ec" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Oct 15 11:50:39 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Oct 15 12:42:03 2009 +0200" }, "message": "events: Harmonize event field names and print output names\n\nNow that we can filter based on fields via perf record, people\nwill start using filter expressions and will expect them to\nbe obvious.\n\nThe primary way to see which fields are available is by looking\nat the trace output, such as:\n\n gcc-18676 [000] 343.011728: irq_handler_entry: irq\u003d0 handler\u003dtimer\n cc1-18677 [000] 343.012727: irq_handler_entry: irq\u003d0 handler\u003dtimer\n cc1-18677 [000] 343.032692: irq_handler_entry: irq\u003d0 handler\u003dtimer\n cc1-18677 [000] 343.033690: irq_handler_entry: irq\u003d0 handler\u003dtimer\n cc1-18677 [000] 343.034687: irq_handler_entry: irq\u003d0 handler\u003dtimer\n cc1-18677 [000] 343.035686: irq_handler_entry: irq\u003d0 handler\u003dtimer\n cc1-18677 [000] 343.036684: irq_handler_entry: irq\u003d0 handler\u003dtimer\n\nWhile \u0027irq\u003d\u003d0\u0027 filters work, the \u0027handler\u003d\u003d\u003cx\u003e\u0027 filter expression\ndoes not work:\n\n $ perf record -R -f -a -e irq:irq_handler_entry --filter handler\u003dtimer sleep 1\n Error: failed to set filter with 22 (Invalid argument)\n\nThe problem is that while an \u0027irq\u0027 field exists and is recognized\nas a filter field -

It has a private ring-buffer implementation that has a number\n of limitations and has been historically fragile and buggy.\n\n - It is using a quirky /dev/mcelog ioctl driven ABI that is MCE\n specific. /dev/mcelog is not part of any larger logging\n framework and hence has remained on the fringes for many years.\n\n - The MCE logging code is still very unclean partly due to its ABI\n limitations. Fields are being reused for multiple purposes, and\n the whole message structure is limited and x86 specific to begin\n with.\n\nAll in one, the x86 tree would like to move away from this private\nimplementation of an event logging facility to a broader framework.\n\nBy using perf events we gain the following advantages:\n\n - Multiple user-space agents can access MCE events. We can have an\n mcelog daemon running but also a system-wide tracer capturing\n important events in flight-recorder mode.\n\n - Sampling support: the kernel and the user-space call-chain of MCE\n events can be stored and analyzed as well. This way actual patterns\n of bad behavior can be matched to precisely what kind of activity\n happened in the kernel (and/or in the app) around that moment in\n time.\n\n - Coupling with other hardware and software events: the PMU can track a\n number of other anomalies - monitoring software might chose to\n monitor those plus the MCE events as well - in one coherent stream of\n events.\n\n - Discovery of MCE sources - tracepoints are enumerated and tools can\n act upon the existence (or non-existence) of various channels of MCE\n information.\n\n - Filtering support: we just subscribe to and act upon the events we\n are interested in. Then even on a per event source basis there\u0027s\n in-kernel filter expressions available that can restrict the amount\n of data that hits the event channel.\n\n - Arbitrary deep per cpu buffering of events - we can buffer 32\n entries or we can buffer as much as we want, as long as we have\n the RAM.\n\n - An NMI-safe ring-buffer implementation - mappable to user-space.\n\n - Built-in support for timestamping of events, PID markers, CPU\n markers, etc.\n\n - A rich ABI accessible over system call interface. Per cpu, per task\n and per workload monitoring of MCE events can be done this way. The\n ABI itself has a nice, meaningful structure.\n\n - Extensible ABI: new fields can be added without breaking tooling.\n New tracepoints can be added as the hardware side evolves. There\u0027s\n various parsers that can be used.\n\n - Lots of scheduling/buffering/batching modes of operandi for MCE\n events. poll() support. mmap() support. read() support. You name it.\n\n - Rich tooling support: even without any MCE specific extensions added\n the \u0027perf\u0027 tool today offers various views of MCE data: perf report,\n perf stat, perf trace can all be used to view logged MCE events and\n perhaps correlate them to certain user-space usage patterns. But it\n can be used directly as well, for user-space agents and policy action\n in mcelog, etc.\n\nWith this we hope to achieve significant code cleanup and feature\nimprovements in the MCE code, and we hope to be able to drop the\n/dev/mcelog facility in the end.\n\nThis patch is just a plain dumb dump of mce_log() records to\nthe tracepoints / perf events framework - a first proof of\nconcept step.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nCc: Huang Ying \u003cying.huang@intel.com\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nLKML-Reference:
