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 took out the old code which was based on a single\nlist.\n\nThe old code (necessarily) had logic which would restart I/O against buffers\nwhich had been redirtied while they were on the committing transaction\u0027s\nt_sync_datalist list. The new code only writes buffers once, ignoring\nredirtyings by a later transaction, which is good.\n\nBut over on the truncate side of things, in journal_unmap_buffer(), we\u0027re\ntreating buffers on the t_locked_list as inviolable things which belong to the\ncommitting transaction, and we just leave them alone during concurrent\ntruncate-vs-commit.\n\nThe net effect is that when truncate tries to invalidate a page whose buffers\nare on t_locked_list and have been redirtied, journal_unmap_buffer() just\nleaves those buffers alone. truncate will remove the page from its mapping\nand we end up with an anonymous clean page with dirty buffers, which is an\nillegal state for a page. The JBD commit will not clean those buffers as they\nare removed from t_locked_list. The VM (try_to_free_buffers) cannot reclaim\nthese pages.\n\nThe patch teaches journal_unmap_buffer() about buffers which are on the\ncommitting transaction\u0027s t_locked_list. These buffers have been written and\nI/O has completed. We can take them off the transaction and undirty them\nwithin the context of journal_invalidatepage()-\u003ejournal_unmap_buffer().\n\nAcked-by: \"Stephen C.
