From c50b91c4bd511dfe844e2aa7be429b6b88406353 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 16 Apr 2012 16:40:56 +0100 Subject: GFS2: Remove bd_list_tr This is another clean up in the logging code. This per-transaction list was largely unused. Its main function was to ensure that the number of buffers in a transaction was correct, however that counter was only used to check the number of buffers in the bd_list_tr, plus an assert at the end of each transaction. With the assert now changed to use the calculated buffer counts, we can remove both bd_list_tr and its associated counter. This should make the code easier to understand as well as shrinking a couple of structures.
