So we have to also count with the case that the\nbuffer has been reallocated and b_next_transaction has been already set.\n\nAnd one more subtle point: it can happen that we manage to reallocate the\nbuffer and also mark it jbddirty.

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.
