Remaining pages can be\nreleased when the system has really few memory. So, it is not memory\nleakage. But the resource management software etc. may not work\ncorrectly.\n\nIt is possible that journal_unmap_buffer() cannot release the buffers, and\nthe pages to which they belong because they are attached to a commiting\ntransaction and journal_unmap_buffer() cannot release them. To release\nsuch the buffers and the pages later, journal_unmap_buffer() leaves it to\njournal_commit_transaction().

But in the ordered mode, jbd does with metadata buffers and also\ndata buffers.\n\nActually, journal_commit_transaction() releases only the metadata buffers\nof which release is demanded by journal_unmap_buffer(), and also releases\nthe pages to which they belong if possible.\n\nAs a result, the data buffers of which release is demanded by\njournal_unmap_buffer() remain after a transaction commits.

Hence affects system\nperformance, particularly on SMP systems and when return probe is set on\nlot of functions (like on all systemcalls).\n\nSolution proposed here gives fine-grain locks that performs better on SMP\nsystem compared to present kretprobe implementation.\n\nSolution:\n\n 1) Instead of having one global lock to protect kretprobe instances\n present in kretprobe object and kretprobe hash table. We will have\n two locks, one lock for protecting kretprobe hash table and another\n lock for kretporbe object.\n\n 2) We hold lock present in kretprobe object while we modify kretprobe\n instance in kretprobe object and we hold per-hash-list lock while\n modifying kretprobe instances present in that hash list. To prevent\n deadlock, we never grab a per-hash-list lock while holding a kretprobe\n lock.\n\n 3) We can remove used_instances from struct kretprobe, as we can\n track used instances of kretprobe instances using kretprobe hash\n table.\n\nTime duration for kernel compilation (\"make -j 8\") on a 8-way ppc64 system\nwith return probes set on all systemcalls looks like this.\n\ncacheline non-cacheline Un-patched kernel\naligned patch \t aligned patch\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m46.784s 9m54.412s 10m2.450s\nuser 40m5.715s 40m7.142s 40m4.273s\nsys 2m57.754s 2m58.583s 3m17.430s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nTime duration for kernel compilation (\"make -j 8) on the same system, when\nkernel is not probed.\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m26.389s\nuser 40m8.775s\nsys 2m7.283s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nSigned-off-by: Srinivasa DS \u003csrinivasa@in.ibm.com\u003e\nSigned-off-by: Jim Keniston \u003cjkenisto@us.ibm.com\u003e\nAcked-by: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: David S.

This new version instead keeps a count on the number of outstanding\nallocations and when it hits zero, it resets the malloc arena.\n\nThis allows removing all the mark and release implementations and unifying\nall the malloc/free implementations.\n\nThe architecture-dependent code must define two addresses:\n - free_mem_ptr, the address of the beginning of the area in which\n allocations should be made\n - free_mem_end_ptr, the address of the end of the area in which\n allocations should be made. If set to 0, then no check is made on\n the number of allocations, it just grows as much as needed\n\nThe architecture-dependent code can also provide an arch_decomp_wdog()\nfunction call. This function will be called several times during the\ndecompression process, and allow to notify the watchdog that the system is\nstill running. If an architecture provides such a call, then it must\ndefine ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls\narch_decomp_wdog().\n\nWork initially done by Matt Mackall, updated to a recent version of the\nkernel and improved by me.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Thomas Petazzoni \u003cthomas.petazzoni@free-electrons.com\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Mikael Starvik \u003cmikael.starvik@axis.com\u003e\nCc: Jesper Nilsson \u003cjesper.nilsson@axis.com\u003e\nCc: Haavard Skinnemoen \u003chskinnemoen@atmel.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: \"H.
