From 2e6db6c4c1f71823472651f162f0b355f5b7951e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 4 Jun 2015 13:47:29 +1000 Subject: xfs: switch remaining xfs_trans_dup users to xfs_trans_roll We have three remaining callers of xfs_trans_dup: - xfs_itruncate_extents which open codes xfs_trans_roll - xfs_bmap_finish doesn't have an xfs_inode argument and thus leaves attaching them to it's callers, but otherwise is identical to xfs_trans_roll - xfs_dir_ialloc looks at the log reservations in the old xfs_trans structure instead of the log reservation parameters, but otherwise is identical to xfs_trans_roll. By allowing a NULL xfs_inode argument to xfs_trans_roll we can switch these three remaining users over to xfs_trans_roll and mark xfs_trans_dup static.
