The patch below\n results in a 4-5x performance improvement (from 6.5MB/s to ~24-30MB/s on my\n IDE test box) when writing out files using O_SYNC.\n\nSo optimise the batching code by omitting it entirely if the process which is\ndoing a sync write is the same as the one which did the most recent sync\nwrite. If that\u0027s true, we\u0027re unlikely to get any other processes joining the\ntransaction.\n\n(Has been in -mm for ages - it took me a long time to get on to performance\ntesting it)\n\nNumbers, on write-cache-disabled IDE:\n\n/usr/bin/time -p synctest -n 10 -uf -t 1 -p 1 dir-name\n\nUnpatched:\n\t40 seconds\nPatched:\n\t35 seconds\nBatching disabled:\n\t35 seconds\n\nThis is the problematic single-process-doing-fsync case. With multiple\nfsyncing processes the numbers are AFACIT unaltered by the patch.\n\nAside: performance testing and instrumentation shows that the transaction\nbatching almost doesn\u0027t help (testing with synctest -n 1 -uf -t 100 -p 10\ndir-name on non-writeback-caching IDE). This is because by the time one\nprocess is running a synchronous commit, a bunch of other processes already\nhave a transaction handle open, so they\u0027re all going to batch into the same\ntransaction anyway.\n\nThe batching seems to offer maybe 5-10% speedup with this workload, but I\u0027m\npretty sure it was more important than that when it was first developed 4-odd\nyears ago...\n\nCc: \"Stephen C.

It does the following\nthings:\n\n - consolidates and enhances the spinlock/rwlock debugging code\n\n - simplifies the asm/spinlock.h files\n\n - encapsulates the raw spinlock type and moves generic spinlock\n features (such as -\u003ebreak_lock) into the generic code.\n\n - cleans up the spinlock code hierarchy to get rid of the spaghetti.\n\nMost notably there\u0027s now only a single variant of the debugging code,\nlocated in lib/spinlock_debug.c. (previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners. There is new spinlock-owner/CPU-tracking on SMP builds too.\nAll locks have lockup detection now, which will work for both soft and hard\nspin/rwlock lockups.\n\nThe arch-level include files now only contain the minimally necessary\nsubset of the spinlock code - all the rest that can be generalized now\nlives in the generic headers:\n\n include/asm-i386/spinlock_types.h | 16\n include/asm-x86_64/spinlock_types.h | 16\n\nI have also split up the various spinlock variants into separate files,\nmaking it easier to see which does what.

I did not try to build\n non-SMP kernels. That should be trivial to fix up later if necessary.\n\n I converted bit ops atomic_hash lock to raw_spinlock_t. Doing so avoids\n some ugly nesting of linux/*.h and asm/*.h files. Those particular locks\n are well tested and contained entirely inside arch specific code. I do NOT\n expect any new issues to arise with them.\n\n If someone does ever need to use debug/metrics with them, then they will\n need to unravel this hairball between spinlocks, atomic ops, and bit ops\n that exist only because parisc has exactly one atomic instruction: LDCW\n (load and clear word).\n\nFrom: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\n\n ia64 fix\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjanv@infradead.org\u003e\nSigned-off-by: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Mikael Pettersson \u003cmikpe@csd.uu.se\u003e\nSigned-off-by: Benoit Boissinot \u003cbenoit.boissinot@ens-lyon.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "022a4a7bbdefdedc2706a13c81c832d8c3173c6d", "tree": "e7bf4f08f02c35b39769a5c2aeeea020c055de99", "parents": [ "202e5979af4d91c7ca05892641131dee22653259" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Tue Sep 06 15:16:41 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:19 2005 -0700" }, "message": "[PATCH] fs/jbd/: cleanups\n\nThis patch contains the following cleanups:\n- make needlessly global functions static\n- journal.c: remove the unused global function __journal_internal_check\n and move the check to journal_init\n- remove the following write-only global variable:\n - journal.c: current_journal\n- remove the following unneeded EXPORT_SYMBOL:\n - journal.c: journal_recover\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nAcked-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
