From bba59c5e4b38e160c6be25b2f4fe36ebc84f53df Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Wed, 11 Jul 2018 22:26:20 -0700 Subject: xfs: add firstblock field to xfs_trans A firstblock var is typically allocated and initialized along with xfs_defer_ops structures and passed around independent from the associated transaction. To facilitate combining the two, add an optional ->t_firstblock field to xfs_trans that can be used in place of an on-stack variable. The firstblock value follows the lifetime of the transaction, so initialize it on allocation and when a transaction rolls.
