This is needed in order to be able to use FSP_EXTENT_SIZE in mtr0log.ic. ------------------------------------------------------------------------ r5127 | vasil | 2009-05-26 17:05:43 +0300 (Tue, 26 May 2009) | 9 lines branches/5.1: Preparation for the fix of Bug#45097 Hang during recovery, redo logs for doublewrite buffer pages Do not include unnecessary headers mtr0log.h and fut0lst.h in trx0sys.h and include fsp0fsp.h just before it is needed. This is needed in order to be able to use TRX_SYS_SPACE in mtr0log.ic. ------------------------------------------------------------------------ r5128 | vasil | 2009-05-26 17:26:37 +0300 (Tue, 26 May 2009) | 7 lines branches/5.1: Fix Bug#45097 Hang during recovery, redo logs for doublewrite buffer pages Do not write redo log for the pages in the doublewrite buffer. Also, do not make a dummy change to the page because this is not needed. ------------------------------------------------------------------------
